Motion sickness is a common problem when travelling in a moving vehicle, especially on land transportation. This occurrence would signify when users are exposed to unexpected movement in an obstructed view. Each user can experience a different level of motion sickness, depending on their susceptibility. This paper aims to study the motion sickness susceptibility among Malaysians using Motion Sickness Susceptibility Questionnaires (MSSQ-Short). A total of 252 Malaysians (146 males and 106 females) completed a set of questionnaires. The questionnaire was distributed through electronic means such as Facebook, WhatsApp, Twitter, and email and consisted of demographic, MSSQ-Short, travel experience as a driver and passenger, and seating position. This study provides a correlation between experiencing motion sickness between childhood and adulthood (r = 0.124, p < 0.05) for the Malaysian sample. This study concludes that Malaysian susceptibility is higher compared to other countries.

Ti-6Al-4V ELI is a well-known, popular medical-grade titanium alloy due to its biocompatibility and excellent mechanical properties. However, like other metal implants, it is less bioactive that affects tissue regeneration around the implant, and may lead to implant failure. So, a bioactive substance such as hydroxyapatite (HA) has usually been coated on metal implants to improve its bioactive properties. However, a single layer of HA was reported to be dissolved into body fluid after a long time of exposure in the human body. In this study, bilayer HA was deposited on the surface of screw-type implants made of Ti-6Al-4V ELI through electrophoretic deposition (EPD method. The bottom layer consists of micro-size of HA, and the second layer contains nano-size HA. The suspension contains each micro and nano size of HA powder was homogenized for 1 h followed by sonication for 2 h using a magnetic stirrer. The coating layer was subsequently sintered at 700oC for 1 h. The bilayer-coated screw implant was then implanted into the proximal tibia of health rattus novergicus under proper surgical procedures. Some screws without HA deposition were also implanted into rattus novergicus for comparison. The implanted screws were then taken out via surgery after 2, 3 and 4 weeks, and they were subsequently observed by optical microscope, SEM and XRF. The results showed that organic material is found on each coated specimen, and few HA layer is disintegrated from the surface of the screw. The disintegrated HA remained in the surface of the screw, and the amount of HA increased with increasing implantation time, which indicates the increase of osseointegration between the bone and HA layer. XRF showed a significant difference in Ti and titanium oxide contents on the surface of the coated samples and the non-coted ones, where it is only 0.66%Ti (0.39% TiO2) on the surface of the screw with HA layer and 70%Ti (67% TiO2) for without HA. When TiO2 is formed as a fast self-healing reaction while the screw is exposed to body fluid, the HA acts as an interface against body fluid that may contain aggressive ions. So, HA layer is not only effective against corrosion attack but also inhibits the formation of TiO2 on the implant surface. The coated screws also revealed a strong bonding between the HA layer and the surface of the implant screw. Besides, the ratio between Ca and P elements on the screw surface is in the range of 0.58 – 2.04, which is in the range of bone characteristics.
Ti-6Al-4V ELI是一种众所周知的、流行的医用级钛合金,因为它具有生物相容性和优异的机械性能。然而,像其他金属种植体一样,它的生物活性较低,影响种植体周围的组织再生,并可能导致种植体失败。因此,生物活性物质如羟基磷灰石(HA)通常被涂覆在金属植入物上以提高其生物活性。然而,据报道,单层透明质酸在人体内长期暴露后会溶解到体液中。本研究采用电泳沉积(EPD)方法,将双层HA沉积在Ti-6Al-4V ELI螺旋型植入体表面。底层是微尺寸的HA,第二层是纳米尺寸的HA。将含有各种微纳米级HA粉末的悬浮液均质1 h,然后用磁力搅拌器超声2 h。涂层层在700℃下烧结1 h,按照适当的手术步骤将双层涂层螺钉植入健康大鼠胫骨近端。一些没有HA沉积的螺钉也被植入黑家鼠体内进行比较。2、3、4周后手术取出植入螺钉,进行光学显微镜、扫描电镜、x射线荧光观察。结果表明:各涂层试样表面均有有机物质存在,螺杆表面有少量HA层崩解;崩解的HA残留在螺钉表面,且随着植入时间的增加,HA的数量增加,说明骨与HA层的骨结合增强。XRF分析表明,涂覆后的螺杆表面Ti和氧化钛含量与未涂覆的螺杆表面Ti和氧化钛含量有显著差异,有HA层的螺杆表面Ti含量仅为0.66% (TiO2含量0.39%),未涂覆的螺杆表面Ti含量为70% (TiO2含量67%)。当螺丝钉暴露在体液中时,TiO2作为一种快速的自愈反应形成,透明质酸作为一个界面来对抗可能含有侵略性离子的体液。因此,HA层不仅可以有效地抵抗腐蚀,还可以抑制种植体表面TiO2的形成。涂覆的螺钉也显示了HA层与种植螺钉表面之间的牢固结合。此外,螺钉表面Ca和P元素的比值在0.58 ~ 2.04之间,在骨特性范围内。

In Malaysia, riding motorcycles is a popular mode of transportation, particularly in urban areas where traffic congestion is prevalent. Additionally, motorcycles are relatively affordable and have low fuel consumption, which makes them an attractive option for many. Per Malaysian traffic laws, riders must wear helmets while riding. As a result, various brands and types of helmets are available for purchase. However, with the increasing popularity of online shopping platforms, many individuals opt to purchase helmets online despite the uncertain quality control of these products. This study aims to assess the effectiveness of three different types of motorcycle helmets in protecting the head from injury. The helmet types evaluated in this unbiased study include full-face, open-face, and half-coverage helmets. The head injury predictors used in this study include Peak Linear Acceleration (PLA), Peak Rotational Acceleration (PRA), Head Injury Criterion (HIC), and Brain Injury Criterion (BrIC). Each helmet was subjected to an impact in a controlled environment using a 6-kg cylinder attached to a pendulum arm, with the impact directed at the front of the helmet at a speed of approximately 6 m/s. Full-face and open-face helmets performed exceptionally well in terms of linear parameters (PLA and HIC). The PLA and HIC of half-coverage helmets are nearly 70% and 50% higher than full-face and open-face helmets. All helmets perform poorly against rotational impact (PRA and BrIC). This shows that helmet design needs to be improved to enhance protection against rotational impact. This study represents the first case study in Malaysia to gather mechanical head injury data comparing the protective performance of different helmet types under both linear and rotational impact. These findings may provide a more accurate understanding of helmet performance in protecting against head injuries.
在马来西亚,骑摩托车是一种流行的交通方式,特别是在交通拥堵普遍的城市地区。此外,摩托车相对便宜,燃料消耗低,这使它们成为许多人的有吸引力的选择。根据马来西亚交通法规,骑车者必须戴上头盔。因此,各种品牌和类型的头盔可供购买。然而,随着网购平台的日益普及,许多人选择在网上购买头盔,尽管这些产品的质量控制不确定。本研究旨在评估三种不同类型的摩托车头盔在保护头部免受伤害方面的有效性。在这项无偏研究中评估的头盔类型包括全面、开放式和半覆盖式头盔。本研究中使用的脑损伤预测因子包括峰值线性加速度(PLA)、峰值旋转加速度(PRA)、脑损伤标准(HIC)和脑损伤标准(BrIC)。每个头盔都在一个受控的环境中受到冲击,冲击的方向是头盔的前部,冲击速度约为6米/秒。全面和开放式头盔在线性参数(PLA和HIC)方面表现得非常好。半罩式头盔的PLA和HIC分别比全罩式和开放式头盔高近70%和50%。所有头盔在抗旋转冲击(PRA和BrIC)方面的性能都很差。这表明,头盔的设计需要改进,以加强对旋转冲击的保护。这项研究是马来西亚第一个收集机械头部损伤数据的案例研究,比较了不同类型头盔在线性和旋转冲击下的保护性能。这些发现可能提供更准确的理解头盔的性能,以防止头部损伤。

There are numerous methods for reducing diesel exhaust emissions. Engine modifications, combustion optimization, and exhaust gas treatment are all popular methods. Another proven method uses fuel additives, such as zinc oxide, copper oxide, and magnesium oxide. Those additives are proven to reduce measured emissions such as carbon monoxide and nitrogen oxide successfully; however, there are still concerns about the toxicity of the emissions, which could harm human health. As a result, carbon nanoparticles have been introduced as a fuel additive due to their low risk to human health. Because of advancements in graphene research, a few researchers began investigating the implications of using graphene nanoplatelets as a fuel additive. The study’s findings appeared to be encouraging. However, no additional research has been identified to forecast the impact on engine emissions other than analyzing the effects of graphene additives on engine emissions. The goal of this study is to forecast the effects of graphene nanoplatelets on diesel engine emissions. The emission parameters of the trial were carbon monoxide, carbon dioxide and nitrogen oxide. The factors considered in the experiment are speed, load, and blend concentration. Response surface methodology and contour plots were generated using Minitab software. The results show that the prediction model’s accuracy is within 10% of the experimental data.
有许多方法来减少柴油废气排放。发动机改装、燃烧优化和废气处理都是流行的方法。另一种经过验证的方法是使用燃料添加剂,如氧化锌、氧化铜和氧化镁。这些添加剂已被证明可以成功地减少测量到的排放,如一氧化碳和氮氧化物;然而,人们仍然担心这些排放物的毒性,这可能会损害人体健康。因此,由于碳纳米颗粒对人类健康的风险较低,它们已被引入作为燃料添加剂。由于石墨烯研究的进步,一些研究人员开始研究使用石墨烯纳米片作为燃料添加剂的影响。这项研究的结果似乎令人鼓舞。然而,除了分析石墨烯添加剂对发动机排放的影响外,还没有其他研究可以预测其对发动机排放的影响。本研究的目的是预测石墨烯纳米片对柴油发动机排放的影响。试验的排放参数为一氧化碳、二氧化碳和氮氧化物。实验中考虑的因素有速度、负荷和混合浓度。使用Minitab软件生成响应面法和等高线图。结果表明,该模型的预测精度在实验数据的10%以内。

This research discusses the static and dynamic analysis of the landing gear structure of an unmanned aerial vehicle (UAV). The dimensional study is conducted to investigate the effect of landing gear dimension variation on UAVs’ static strength and dynamic response. Static analysis was performed with Finite Element Method (FEM) software. The dynamic response of the UAV is analyzed using a single-degree-of-freedom vibration model. Based on the static analysis results, the landing gear stiffness and strength can be increased by increasing the width and decreasing the height, radius, and length of the landing gear structure. The energy dissipation in the dynamic analysis is described by hysteresis and viscous damping model. The dynamic response simulation results show that the increase in the stiffness of the landing gear leads to an increase in force transmission and acceleration of the UAV. Furthermore, the UAV response using the viscous damping model can accurately predict the system’s response with the hysteretic damping model for small damping conditions. However, the deviation was observed for large damping conditions.
对某型无人机起落架结构进行了静动力分析。为研究起落架尺寸变化对无人机静强度和动态响应的影响,进行了尺寸研究。采用有限元软件进行静力分析。采用单自由度振动模型对无人机的动态响应进行了分析。根据静力分析结果,可以通过增大起落架结构的宽度,减小起落架结构的高度、半径和长度来提高起落架的刚度和强度。动力分析中的能量耗散用滞回和粘性阻尼模型来描述。动态响应仿真结果表明,起落架刚度的增加会导致无人机的力传递和加速度的增加。此外,在小阻尼条件下,采用粘性阻尼模型的无人机响应可以准确地预测采用滞回阻尼模型的系统响应。然而,在大阻尼条件下观察到偏差。

Effect of Microwave Hybrid Heating on Mechanical Properties and Microstructure of Sn3.0Ag0.5Cu/Cu Solder Joints 微波复合加热对Sn3.0Ag0.5Cu/Cu焊点力学性能和组织的影响

Microwave hybrid heating (MHH) has become soldering’s alternative method for lead-free solder alloys due to its benefits towards modern microtechnology, such as shorter processing time, lower energy consumption and lower defect rate. Nonetheless, it still requires susceptors to improve its heating performance, such as SiC, which is known for its high loss factor under low microwave frequencies. In this study, the effect of microwave hybrid heating on mechanical properties, as well as the microstructure of solder joint between Sn3.0Ag0.5Cu (SAC305) solder alloy and Cu substrate was investigated. Solder joint was created using MHH with different soldering parameters (amount of SiC in a range of 3-7g and exposure time in a range of 7-10min) between SAC305 solder alloy (in the form of wire and paste) and Cu substrate. Then, a lap shear test was carried out following a standard of ASTM D1002 to determine solder joint strength. Characterization was made using an optical microscope and scanning electron microscopy. Results showed that solder wire produced the highest solder joint strength with the value of 115.45 MPa when using 3.05g of SiC for 8.92min soldering time. Meanwhile, the solder paste produced 109.76MPa solder joint strength when using 3.03 g of SiC for 9.39 min soldering time. The intermetallic compound (IMC) form was scallop-like Cu6Sn5, both solder/substrate joints with a thickness of 2.87 μm for solder wire and 3.62 μm for solder paste. Nonetheless, an excessive amount of SiC would generate more heat in MHH and increase the IMC thickness as well as reduce shear strength, which eventually decreases the solder joint stability.
微波混合加热(MHH)由于其对现代微技术的优点,如加工时间短、能耗低和缺品率低,已成为无铅焊料合金焊接的替代方法。尽管如此,它仍然需要感受器来改善其加热性能,例如以低微波频率下的高损耗因子而闻名的SiC。在本研究中,研究了微波复合加热对Sn3.0Ag0.5Cu (SAC305)钎料合金与Cu衬底的力学性能和焊点组织的影响。在SAC305焊料合金(以线材和膏体的形式)和Cu衬底之间,采用不同焊接参数(SiC用量在3-7g范围内,暴露时间在7-10min范围内)的MHH制作焊点。然后,按照ASTM D1002的标准进行搭接剪切试验,以确定焊点强度。利用光学显微镜和扫描电镜对其进行了表征。结果表明:当SiC用量为3.05g,焊接时间为8.92min时,焊丝的焊点强度最高,为115.45 MPa;同时,当SiC用量为3.03 g,焊接时间为9.39 min时,锡膏的焊点强度为109.76MPa。金属间化合物(IMC)形态为扇贝状Cu6Sn5,焊锡线厚度为2.87 μm,焊膏厚度为3.62 μm。然而,过量的SiC会在MHH中产生更多的热量,增加IMC厚度,降低抗剪强度,最终降低焊点的稳定性。

Nonetheless, it still requires susceptors to improve its heating performance, such as SiC, which is known for its high loss factor under low microwave frequencies. In this study, the effect of microwave hybrid heating on mechanical properties, as well as the microstructure of solder joint between Sn3.0Ag0.5Cu (SAC305) solder alloy and Cu substrate was investigated. Solder joint was created using MHH with different soldering parameters (amount of SiC in a range of 3-7g and exposure time in a range of 7-10min) between SAC305 solder alloy (in the form of wire and paste) and Cu substrate. Then, a lap shear test was carried out following a standard of ASTM D1002 to determine solder joint strength. Characterization was made using an optical microscope and scanning electron microscopy. Results showed that solder wire produced the highest solder joint strength with the value of 115.45 MPa when using 3.05g of SiC for 8.92min soldering time. Meanwhile, the solder paste produced 109.76MPa solder joint strength when using 3.03 g of SiC for 9.39 min soldering time. The intermetallic compound (IMC) form was scallop-like Cu6Sn5, both solder/substrate joints with a thickness of 2.87 μm for solder wire and 3.62 μm for solder paste. Nonetheless, an excessive amount of SiC would generate more heat in MHH and increase the IMC thickness as well as reduce shear strength, which eventually decreases the solder joint stability.","PeriodicalId":13935,"journal":{"name":"International Journal of Automotive and Mechanical Engineering","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136077337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on the fatigue behaviour analysis of glass fibre-reinforced polymer (GFRP) composite specimens under high-cycle fatigue loading conditions. Therefore, property validation is recommended in the material development process upon further investigation of the fabricated GRFP. This study aims to evaluate the behaviour of the fabricated GFRP fatigue specimen when subjected to high-cycle fatigue loads and compare it to existing studies. A GFRP fatigue test sample was fabricated using the hand layup process into a flat rectangular panel, which was then cut into a small dimension of 28×2×0.2 cm fatigue specimen. Fatigue tests were performed on five flat specimens at different constant amplitude loads or stress levels between 40% and 80% of ultimate tensile strength to obtain the stress–life curve for the fabricated GFRP. Results showed that the high-stress levels of 80% contributed to the most reduced fatigue life cycle of GFRP. This result is consistent with previous studies and lies within the published life cycle range, validating the fabricated GRFP. A new parameter called the failure modulus, or Mf, may be used to quantify a particular set of fatigue tests.
本文研究了玻璃纤维增强聚合物(GFRP)复合材料试样在高周疲劳加载条件下的疲劳行为分析。因此,建议在材料开发过程中对制备的GRFP进行进一步研究后进行性能验证。本研究旨在评估制备的GFRP疲劳试样在高周疲劳载荷下的行为,并将其与现有研究进行比较。采用手工叠层法将GFRP疲劳试样制作成矩形平板,然后将其切割成28×2×0.2 cm的小尺寸疲劳试样。在不同的等幅载荷或在极限抗拉强度的40% ~ 80%之间的应力水平下,对5个平面试样进行疲劳试验,得到了制备的GFRP的应力-寿命曲线。结果表明,80%的高应力水平对GFRP疲劳寿命周期的缩短贡献最大。这一结果与以往的研究结果一致,并且在已发表的生命周期范围内,验证了制备的GRFP。一个叫做失效模量(Mf)的新参数可以用来量化一组特定的疲劳试验。

This paper presents a gearbox defect diagnosis based on vibration behaviour. In order to record the vibration response under various circumstances, an industrial gearbox was used as the basis for an experimental setup. The signals resulting from gear wear were processed using an empirical mode decomposition for two operating time intervals (zero-hour running time and thirty-hour running time). The first three intrinsic mode functions and the corresponding frequency response were detected. The ten statistical parameters most sensitive to gear wear were selected using an evaluation method based on Euclidean distance. Using the identified features, an artificial neural network (ANN) was trained to track the gearbox for the selected future data set. The neural network received its input from the statistical parameters, and its output was the number of gearbox running hours. To achieve faster convergence, the radial basis function and the backpropagation neural network were compared. The superiority of the proposed strategy is demonstrated by comparing the performance of ANN. For monitoring the condition of industrial gears, the proposed strategy is found to be effective and trustworthy.

A power converter is one of the important components in a hybrid electric vehicle (HEV), where it has a strong nonlinear dynamic due to the variation of load demand from different driving modes, namely acceleration, braking and cruising. To adapt with the nonlinearities, this work proposes the use of direct model reference adaptive control (DMRAC) to regulate its operation in tracking the load and current demand of the HEV. To validate the response, the control performance is benchmarked with the commonly used traditional PI controller. The system model includes a battery with a supercapacitor, and its controller was constructed using the MATLAB Simulink platform. Simulation results show that DMRAC provides better performance as compared to the PI controller in two cases, which are tracking the current and load demands according to the root mean square error (RMSE) analysis. Nevertheless, in the presence of disturbance, it is noted that DMRAC is only effective in tracking the current demand while requiring some time to adapt and surpass the PI controller in tracking the load demand. Based on these findings, it can be justified that the DMRAC has the potential to become a good alternative approach to control the HEV power converters, specifically in the presence of disturbance.
功率变换器是混合动力汽车的重要部件之一,在加速、制动和巡航等不同驾驶模式下,由于负载需求的变化,功率变换器具有很强的非线性动力学特性。为了适应混合动力系统的非线性特性,本文提出采用直接模型参考自适应控制(DMRAC)对混合动力系统的负载和电流需求进行跟踪。为了验证响应,用常用的传统PI控制器对控制性能进行了基准测试。该系统模型包括一个带超级电容器的电池,并利用MATLAB Simulink平台构建了其控制器。仿真结果表明,在根据均方根误差(RMSE)分析跟踪电流和负载需求的两种情况下,DMRAC比PI控制器具有更好的性能。然而,在存在干扰的情况下,需要注意的是,DMRAC仅在跟踪当前需求时有效,而在跟踪负载需求时需要一些时间来适应并超越PI控制器。基于这些发现,可以证明DMRAC有可能成为控制HEV功率转换器的一种很好的替代方法,特别是在存在干扰的情况下。
