This paper presents an analysis of the design of the bogie pivot of an electric multiple unit, which is cast in cast steel to replace the forged pivot used to date. The change in pivot manufacturing technology is justified for eco - nomic reasons, but may affect the reliability and operational safety of multiple units. The authors analysed to what extent the change in pivot manufacturing technology from forged to cast can affect the operational reliability of the upgraded structural component and what requirements should be met so that the introduced upgrade does not reduce the operational safety of the electric multiple unit. An important part of the analysis is the consideration of the effect of preventive replacements of the rubber element of the vibration damper on damage to the pivot and vibra - tion damper system. The dependence of damage to the cooperating components of the pivot elements and vibration damper in the system is demonstrated. The lifespan of the rubber element of the damper is considerably less than that of the bogie pivot of the electric traction unit, and its damage increases the probability of damage to the cast steel pivot. This relationship is critical and, in order to ensure the required reliability of the traction unit, a strategy of preventive replacement of the rubber element of the damper was proposed and achieved in the simulation model developed. This issue is presented in this paper because it is fundamental to the safe operation of rail vehicles.

This paper presents a machine learning and image segmentation based advanced quality assessment technique for thin refill friction stir spot welded (RFSSW) joints. In particular, the research focuses on developing a predictive support vector machines (SVM) model. The purpose of this model is to facilitate the selection of RFSSW process parameters in order to increase the shear load capacity of joints. In addition, an improved weld quality assessment algorithm based on optical analysis was developed. The research methodology includes specimen preparation stages, mechanical tests, and algorithmic analysis, culminating in a machine learning model trained on experimental data. The results demonstrate the effectiveness of the model in selecting welding process parameters and assessing weld quality, offering significant improvements compared to standard techniques. The optimized SVM model, employing the radial basis function (RBF) kernel, achieved a lower root mean square error of 257.9 and a high correlation coefficient of 0.95, indicating a strong linear relationship between the predicted and actual shear load capacities. This research not only proposes a novel approach to optimizing welding parameters but also facilitates automatic quality assessment, potentially revolutionizing and spreading the application of the RFSSW technique in various industries.

The article presents the concepts of control systems that use methods of automatic analysis and interpretation of signals. These issues are presented through the description of three control strategies: simple closed-loop control, control using a process of classification, and using a signal understanding technique. The systems based on the discussed concepts are illustrated with examples of controlling a milling machine and an autonomous vehicle. In addition, in more detail, a task of learning human motor activities is described. This task, due to the nature of the controlled object, which is a human being, is extremely difficult. The article shows that the advanced control process, in which the control algorithm is selected and its parameters are adapted to the current situation, may be implemented through the use of the classification process and machine learning methods in general. Changing the algorithm is also possible using signal understanding techniques. These techniques, utilizing models of the objects, allow to predict the long-term effects of the control process. The ability to build control systems that operate in the above manner is of huge practical importance. The aim of this article is to describe the methods of automatic signal interpretation used in control processes and identify the main problems related to their use. The key problems refer to the acquisition of expert knowledge by the system. In order for this knowledge to be effectively transferred, the methods used in the system should have a high level of explainability. Showing the essential nature of this feature is the main outcome of this work.

The emerging trend of employing 4 or more axes multi-purpose and gantry industrial robots in large format additive manufacturing presents numerous opportunities as well as challenges. The capacity to handle substantial material quantities and rapidly produce prototypes, instrumentation, and final products of considerable dimensions necessitates the formulation of a well-suited production strategy. This involves setting production parameters to minimize material consumption and production time, considering the limitations of the utilized technologies, and ensuring the final product’s quality. While slicers are commonly employed for establishing manufacturing strate - gies and production parameters, most additive manufacturing slicers are optimized for planar 3 axes 3D printing. This limitation hinders their ability to generate non-planar and freeform toolpaths. To overcome this constraint, this paper delves into the utilization of parametric modelling as a potent tool in the realm of non-planar additive manufacturing. It explores the possibilities offered by Rhinoceros Grasshopper software in designing toolpath strategies and fabricating non-planar layers. The paper addresses the associated challenges and limitations of parametric modelling, including computational complexity and the requirement for specialized software and expertise. It emphasizes the crucial need to strike a balance between design complexity and manufacturability to ensure the successful implementation of non-planar additive manufacturing processes.

This paper aimed to determine the susceptibility of polycarbonate and polymethylmethacrylate to corrosion cracking under specific operating conditions. The tests included static tensile and flexure, impact strength, and micro - scopic examination. Due to the synergistic effect of tensile stresses and seawater environment, numerous cracks are observed. Moreover, aging conditions did not significantly reduce the strength properties of the tested speci - mens; thus, higher resistance to stress corrosion cracking does not have a close relationship with the material’s mechanical properties.

The article presents the study of the light transmittance of a colorless car varnish. The varnish was tested at different temperatures for UV light transmission and the ability to protect car paint pigments from degradation. These tests make it possible to assess the durability and quality of the varnish. A comparison of light transmittance through glass, quartz glass and solar glass was made. It has been noted that the curing temperature of the varnish has an impact on its transmission (up to a few percent). A similar effect has been observed in the case of varnish with a hardener.

This research paper explained in detail how well regular concrete works and how well concrete with fly ash and ground granulated blast furnace slag (GGBS) performs as a substitute for cement. Through a series of experiments, the objective of the study was to perform an experiment that promotes the usage of partial replacement-based concrete which can replace the conventional concrete as well as contributes to sustainable development. A dedicated methodology was developed for the study, focusing on the mechanical and durability properties of the materials with inducing sustainable materials. The methodology study examined the mechanical properties, durability, and microstructural attributes of concrete blends. Cement concrete specimens with binder ratios (%) of 0.3, 0.4, and 0.5 were tested for compressive strength, rapid chloride permeability, SEM, and XRD at 28, 56, and 90 days. Fly ash and GGBS were used to partially replace cement at 0% to 70% for all binder ratios by weight of cement. There were optimal replacement percentages for each binder ratio and fly ash; the concrete partially substituted with GGBS had similar or enhanced mechanical properties to conventional concrete. The novelty of the study is to incorporate microstructure analysis for the same samples that shall enable analysing the behaviour of the partial replaced materials with conventional concrete. In connection with the results, the study had found lower RCPT values in partial replacement concrete specimens, fly ash and GGBS increased chloride ion resistance. SEM and XRD analyses revealed the microstructural properties and phase composition of concrete mixtures, showing how supplementary cementitious materials refine pore structure and provide durable hydration products. This study shows that fly ash and GGBS can improve concrete performance as well as reduce impact on environment and applications in construction.

This study goes on the enhancement of thermal performance of a chimney type electrically heated hot storage tanks (HST) in static mode. The different natural circulation areas (chimney areas) were used with different di - ameter of large (9.5 cm), medium (2.5 cm) and small (1.5 cm) to find the effect of natural circulation on HST performance. Being part of real system, the performance of chimney insulated and without chimney insulation was also studied. The experiments showed that the chimney significantly affects the thermal stratification within the tank. Different chimney contact diameters (9.5 cm, 2.5 cm and 1.5 cm) were tested giving varying degrees of thermal stratification. It was found that the smaller chimney contact diameters led to higher thermal stratification that gives a more rapid heating of the top layer temperatures. The impact of insulation on thermal performance was inconclusive as top layer temperatures of the tank were still rising, showing the need of a more effective insulation as well as further investigation into the dynamic mode of operation. It is also noted that the top outer layer had the higher rate of temperature rising to the larger diameter, giving the sign of the importance of the chimney type electrical heater in the hot storage tank.

This study combined simulation and experimental tests to analyse the cutting performance of three solid carbide end mills with distinct geometries during the milling of the 7075 aluminium alloy. For the tests, three uncoated end mills were employed, which differed in rake angle, clearance angle, and helical pitch. Simulation tests revealed temperature distributions and the resultant cutting forces. The machining with a milling cutter with a higher blade angle was shown to cause an increase in the temperature in the cutting zone. However, during machining with a sharper blade of cutting tool, a decrease of cutting forces was not observed. The simulated temperature distribution on the cutting edge of the cutting tool may justify significant differences in the dynamics of changes in the cutting force components during the period of operational wear.

The simulated temperature distribution on the cutting edge of the cutting tool may justify significant differences in the dynamics of changes in the cutting force components during the period of operational wear.","PeriodicalId":517116,"journal":{"name":"Advances in Science and Technology Research Journal","volume":"4 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141234021","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}
