Abstract

ATMI Duta Engineering company is a manufacturing company engaged in the field of sheet metal with a material cutting process using laser cutting technology. Sheet metal products produced at ATMI Duta Engineering company is very diverse, one of which is the base cabinet. The base cabinet has main components, one of which is the shelf. Based on the data obtained from the interview process, there are problems, namely the shelf has never been analyzed, there are no finished products, and there is a risk of damage due to excessive loading. The solution to the shelf problem is to carry out a shelf design analysis using the finite element analysis method through Solidworks CAE software. The CAE simulation was applied to 27 variations of the shelf design by combining 3 test variables, namely the shelf model, the reinforcement model, and the thickness of the material. The material used in the simulation is SPCC material with a thickness of 1mm, 1.2mm and 1.5mm. The CAE simulation results obtained are then compared with reference to the SEFA 8M-2016 standard. The loading given in the CAE simulation is ± 108 kg (1.2 SEFA standards). The strongest variation obtained from the elimination process is variation 19 with a combination of shelf model 1 design, reinforcement model A, and with a material thickness of 1.5mm. Variation 19 meets the SEFA 8M-2016 standard because the displacement value is 1.065mm and this value is smaller than 6.35mm.

Abstract

An important component of an electric motorcycle is the battery, which plays a role in storing energy through the principles of electrochemistry. Lead-acid and lithium-ion batteries are the two most common types of batteries found in electric vehicles. Electric motorcycle batteries typically range from 32 to 72 volts, depending on engine requirements, and have a storage capacity of 20 to 50 Ah. Batteries generally have internal resistance that causes temperature increases, which means that working at high temperatures will significantly decrease their life. Increased temperatures can also create heat leaks inside the battery, which can lead to major safety issues such as fires and explosions, as well as a loss of battery capacity. The working temperature should not be kept above 50 °C, whereas on lithium-ion batteries, it ranges between -30 °C and 40 °C. The aim of this research is to develop, manufacture, and test battery boxes with passive cooling to keep the battery temperature at the intended ideal level. The method applied is to set up a control system that can function to prevent overheating the battery. Based on the tests carried out on the passive cooling system, this managed to maintain the temperature of the lithium-ion battery when used at an average speed of 40–60 km/h.

Abstract

A flying car can fulfill two functions, as a vehicle on the road and as an airplane that capable of flying. To reduce aerodynamic drag, the drive wheels must be able to fold so that a flexible transmission system is required. The Hydrostatic Transmission (HT) system is a flexible transmission that uses a hose to connect hydraulic pump, which is coupled to the engine, to hydraulic motor, which is coupled to the wheel. This research analyzes the specifications of hydrostatic transmission components to optimally transmit power from a V6 engine to two drive wheels through a speed gear transmission system. The hydrostatic transmission system specifications, which include pumps, motors, hoses, charge pumps, and release valves, are analyzed using Simscape MATLAB software. This software enables the user to easily modify the parameters to build an optimal hydrostatic transmission design. To ensure optimal performance of the entire flying car propulsion system, a 60kW pump and 20kW motor are required.

Abstract

This study aims to analyze the comparison between injection molding simulations in Autodesk Moldflow software and the products produced. Simulations are carried out to estimate the presence of production defects in objects, without having to produce the object first. In the simulation, the occurrence of production defects is estimated according to the parameters that have been entered. These production defects include short shots, flash, flowmarks, weld lines, and bubbles. In the production results, defects were found that had been predicted by previous simulations. The simulation results can be considered to be able to predict production defects that will occur in the production process.

Abstract

Aluminum, with a thermal conductivity close to 2/3 that of copper, can utilize friction welding effectively. Chamfer angles improve the welding quality by increasing the generated heat, resulting in higher mechanical properties. This study investigates the impact of chamfer angles (15°, 30°, and 45°) on the microstructure and tensile strength of friction-welded Al 6061 under conditions of 1600 rpm rotation, 50 MPa forging pressure, 20 MPa friction pressure, and 45 seconds of welding time. Microstructure and tensile strength tests were conducted on three specimens for each chamfer angle. Results show that increased friction time, friction pressure, and forging pressure lead to greater material loss due to flash formation. Microstructure analysis revealed that chamfer angles of 30° and 45° achieved better welding at the interface due to sufficient heat generation. In the heat-affected zone (HAZ), all angles (15°, 30°, and 45°) showed phase structure changes, with broader and more uniform Mg2Si and Fe3SiAl12 phases, attributed to the cooling process and relatively low heat. Tensile testing showed the highest tensile strength (177.9 MPa) and strain (6.42%) for the 30° chamfer angle, outperforming the 15° and 45° angles. The smallest strain (3.72%) was observed in the 15° chamfer angle, indicating the significant influence of chamfer geometry on friction welding outcomes.

Abstract

The increase in people's mobility were reflected in the growing sales of motor vehicles. This has driven automotive manufacturers to compete in creating more powerful and efficient engines. These engines were designed with high compression ratios to achieve greater efficiency. High compression ratio engine re-quired fuel with the appropriate octane number to attain opti-mal performance. It is regrettable that many users had not un-derstood that an engine with high compression had required gasoline with a high octane rating as well. This research aims to investigate the impact of different compression ratios on the output power and torque of a single-cylinder combustion en-gine using RON 92, RON 95, and RON 100 gasoline. To modify the compression ratio, various numbers of gaskets were used on the cylinder head, with 2 and 3 gaskets for each configuration. A dynamometer test was employed to measure the differences in engine performance. The research results indicate that the engine with the highest compression pressure (11 Kg/cm2) using RON 100 gasoline produced the highest power of 7.90 kW, with the highest torque of 9.60 Nm. Conversely, the engine with the lowest compression pressure (10 Kg/cm2) using RON 92 gasoline produced the lowest power and the lowest torque.
