The development of a methodology for calculating the designed strength of an unconventional kingpin-type load-carrying system for the articulated tractor container carrier on pneumatic wheels is an important and relevant task due to the unique layout of a given specialized vehicle. The purpose of this work is to devise a procedure for calculating the designed strength of a clip load-carrying system for the articulated tractor container carrier on pneumatic wheels, aimed at building an improved structure with rational metal consumption. The results of the theoretical and experimental studies have determined the most common estimation cases. They include the movement over the technological roads' irregularities along the horizontal section of the road ‒ an estimation case of the semi-trailer frame girders. climbing a high curb at an angle was also considered as an estimation case for the semi-trailer frame girders and cross member. Starting a tractor container carrier forward with an insurmountable obstacle in front of the semi-trailer's wheels was analyzed as an estimation case for the cross member of the frame and the suspension attachment units in the semi-trailer of a tractor container carrier. The result of the reported theoretical and experimental research is the determined load that acts on one cradle structure of the load-carrying system; it forms the torsional rigidity of the frame structure. Underlying the derived mathematical model for each case are the torsional moments and inertia moments that act on the structural elements of the girder in different planes. The mathematical models have been built on the basis of strength conditions for each estimation case and thus form a mathematical formula for determining the wall thickness of the frame girder. The mathematical notation demonstrates the degree of advantage of climbing a high curb at an angle over other estimation cases for the semitrailer frame member and girders. The estimation parameters underlying the mathematical model are meant to prevent the breaking and torsion of the semi-trailer frame in a tractor container carrier

Design of a low-profile and compact circularly polarized microstrip antenna is proposed and investigated based on fractal radiator and high impedance metasurface. Circular polarization and size reduction is achieved by embedding fractal tree like structures at the corners of a square patch. High impedance metasurface is placed at the half of the total height of the FR4 substrate, to enhance the gain of the proposed antenna. Study revealed that the antenna is very compact with layout of 0. 3λ0 x 0.3 λ0 x 0 .012 λ0 at 2.3 GHz, global bandwidth (reflection coefficient, axial ratio and gain bandwidth) of 16 MHz (2.293 GHz - 2.309 GHz) and stable gain of about 2.5 dBic. Proposed Design is single feed and small sized, therefore can be find applications in many portable/IOT wireless communication systems.

The vehicle structure, designs and materials on school bus body crashworthiness as regulated by different government agencies in bus body building firms was the topic under research study. In Kenya, thousands of vehicles are involved in vehicle collisions or crashes every year resulting in fatal accidents and severe injuries to the passengers. The specific objective was the influence of vehicle inspection testson crashworthiness of school bus in Nairobi City County. This study adopted Dym’s, Suh’s Axiomatic theory. The pragmatic paradigm and explanatory research design were used. The target population was 1500 respondents from bus body building firms and government regulatory institutions. The sample size was 315 respondents. Questionnaires, interview schedules and observation were data collection instruments. Expert judgment was used to establish validity of the questionnaires. Cronbach’s Alpha Coefficient was used to determine the reliability of the research instrument. The data collected was analyzed using descriptive and inferential analysis with the aid of SPSS V22 software. The coefficient of determination (R squared) of .206 showing that 20.6% of the variation in crashworthiness of a bus can be explained by vehicle inspection tests. There was a positive significant influence of vehicle inspection tests on crashworthiness of a bus (β=0.396 and p <0.05). The study concluded that the vehicle inspection tests had a significant influence on the crashworthiness of school bus. The management of school bus body construction companies need to conduct all the terminal test needed before releasing the vehicle in order to enhance crashworthiness of a bus. The Transport authority should examine and check the mandatory requirements and periodically amend them in accordance with the safety, engineering and ecological standardization.
对校车车身制造企业的车身结构、设计和材料对不同政府部门规定的校车车身耐撞性进行了研究。在肯尼亚,每年有成千上万的车辆发生碰撞或撞车事故,导致致命事故和乘客严重受伤。具体目的是研究车辆检验试验对内罗毕市县校车耐撞性的影响。本研究采用Dym’s, Suh’s Axiomatic理论。本文采用了语用范式和解释性研究设计。调查对象是1500名来自巴士车身制造公司和政府监管机构的受访者。样本量为315名受访者。问卷调查、访谈计划和观察是数据收集的工具。采用专家判断法确定问卷的效度。采用Cronbach’s Alpha系数来确定研究仪器的可靠性。采用SPSS V22软件对收集到的数据进行描述性和推理性分析。决定系数(R平方)为0.206,表明客车耐撞性变化的20.6%可以通过车辆检验试验来解释。车辆检验试验对客车耐撞性有显著正影响(β=0.396, p <0.05)。研究表明,车辆检验测试对校车的耐撞性有显著影响。为了提高校车的耐撞性,校车车身制造公司的管理层需要在放行车辆之前进行所有必要的终端测试。交通运输主管部门应根据安全、工程和生态标准对强制性要求进行审查和检查,并定期进行修订。

Have you asked yourself how you will look over 15 years? At the Bosch factory in Jucu, we saw a time machine that can help you to travel for 15 years in the future. And the technologies used seem to have come from the reality of the next decades. This "time machine" is, in fact, part of Bosch's Engineering, Quality and Validation Laboratory (EQV). It's the test room, where the products are "aged" for 15 years to analyze how they can withstand the passage of time and the action of natural phenomena - storm, equatorial rain or frost. The EQV lab concept was created from the idea of synergy between R&D departments and production, a configuration that can provide a holistic view of Bosch products that are being analyzed from the initial development phase of the product until the product returns to the laboratory to investigate possible defects that occurred during their use. "We test the product's resistance to equatorial rain, for example. If it is an electronic component mounted on a machine that will go to South America and we know that there is very high humidity in that area, here we simulate the aging of samples in a more accelerated way, "explains Grasim Robert, head of the analysis group of the EQV lab. But they are not the only tests the products are subjected to. The water resistance of the samples is also done with a very strong 6 bar jet and the water has a force similar to that coming from a fire hose. Other tests check for resistance to different types of dust - for example, Arizona powder is more abrasive and worn plastic components, while ash-containing dust can lead to short-circuits - or saline mist, which activates corrosion mechanisms. In the climatic rooms, explains Grasim Robert, there are several parameters: Time, temperature and humidity. Depending on ISO standards and customer requirements, the test team varies these three physical parameters. There are tests that last for 10-12 months. In other words, a 15-year journey in the future still takes a few months, but taking into account the pace with which technology evolves, it is obvious that this duration is reduced.

This paper delineates the layout and the detailed design of a single input multiple output (SIMO) gearbox for a strip leveller machine. The leveller machine is used to flatten out and level the coiled sheets for finding applications in various industries. Roller leveling is essentially a bending process. The out of flat part, sheet or plate is deformed by a series of alternating bends created by passing the sheet, or plate between upper and lower sets of leveling rollers. The power is transmitted to the rollers from the motor via a gearbox and the outputs of the gearbox are connected to the rollers through spindle shafts with the help of universal joints. The large angle of these universal joints affects its efficiency and thereby decreases its life. Hence this angle is to be reduced and one way of achieving this is by compacting the gearbox. The size is drastically reduced by constructing the layout of the gears in such a way, that the space between the outer surface of the gear and the shaft is utilized by arranging the gears in several lateral and longitudinal planes. The main aim of the paper is to describe this innovative layout and its design verification.

Internal combustion engines in line (regardless of whether the work in four-stroke engines and two-stroke engines Otto cycle engines, diesel and Lenoir) are, in general, the most used. Their problem of balancing is extremely important for their operation is correct. There are two possible types of balancing: Static and dynamic balance. The total static to make sure that the sum of the forces of inertia of a mechanism to be zero. There are also a static balance partial. Dynamic balance means to cancel all the moments (load) inertia of the mechanism. A way of the design of an engine in a straight line is that the difference between the crank 180 [°] or 120 [°]. A different type of construction of the engine is the engine with the cylinders in the opposite line, called "cylinder sportsmen". In this type of engine (regardless of their position, which is most often vertical) for engines with two cylinders, one has a static balance total and an imbalance in the dynamic. Similar to the model of the earth concentrated in rotation movement are resolved and load balancing shafts rotating parts. An important way to reduce losses of heat engines is how to achieve a better balance. The methods may be used in equal measure and on engines with external combustion, type Stirling or Watt.
