Abstract

This study used finite element analysis method to analyze the underbracket T triangle on motorcycles using ANSYS 2023 R1 software. The material used is Structural Steel. The simulation is done by accurately modeling the triangle and meshing using the default algorithm. The boundary conditions are set by providing fixed support at all four-hole points and providing a load of 1000N on the Y-axis. The simulation results show a maximum equivalent stress (Von-Mises stress) of 7.173 MPa, which is still below the strength limit of the material. The underbracket T-triangle undergoes a maximum deformation of 0.00063309 mm at the upper right fork hole. This deformation indicates the extent to which the triangle changes shape due to the load applied. The safety factor obtained is greater than 1, indicating that the triangle has adequate safety to withstand the load. With a better understanding of the structural behavior of the underbracket triangle, the design can be improved to improve the strength and performance of the motorcycle.

Abstract

This study used an experimental research method, which is a research method that aims to understand the causal process by treatment and conducting controlled testing on a sample of research subjects. This research uses quantitative methods by taking research data in the form of numbers. The material used in this study is the gear sprocket. A gear sprocket is a motor component that transmits power from the engine to the rear wheels so that the motor can run optimally. The sprocket gear was heat treated at 850 ℃ with a holding time of 20 minutes. The variations of quenching media are mineral water, dromus coolant, and SAE 40 oil. Hardness and microstructure tests were carried out for each specimen to determine the effect of different cooling media on the quenching process. The results of this study indicate the highest specimen hardness value was obtained at 301 HV by immersion in mineral water media. The lowest hardness was obtained at 207 HV with SAE 40 oil media immersion. Meanwhile, the non-treatment material hardness is 150 HV. In this case, there was an increase in the highest hardness of about two times compared to non-treated specimens. Observation of the microstructure shows that the grain size of the mineral water quenching specimens looks smaller than that of the non-treatment models. This phenomenon supports the idea that quenching can increase the surface hardness of the gear sprocket.

Abstract

Pressure losses in the piping system cause additional power to the pump which also causes additional operational costs. The main cause of pressure losses in the piping system is the unevenness of the inside area of the pipes and accessories. This research analyzes the piping system in PUD. Medan Slaughterhouse, starting from the loss of compressive energy, capacity, flow speed, efficiency, and power of the piping system and recommending a better piping system than the existing one. Data on the piping system at PUD. Medan Slaughterhouse was analyzed using fluid mechanics equations such as the Darcy-Weisbach equation and then compared with the results of pipe flow simulation calculations.

Abstract

The sprocket and chain transmission system was used to transmit the rotating force that occurs between two shafts where they can reach it. The sprocket and chain transmission system transfers a movement from the driving source to the moved object. If the maintenance of the sprocket and chain transmission system is carried out only occasionally, the sprocket and chain may cause misalignment. That can affect the machine's performance and cause a breakdown of the machine's components. This study aims to determine the effect of misalignment on the electric current usage and shaft rotation speed in the sprocket and chain transmission system. The leading equipment used in this study is a sprocket and chain alignment kit, while the auxiliary equipment used are ampere meter, tachometer, and other equipment. Measurements of electric current and shaft rotational speed were carried out with a variation of misalignments. The study results show that the increase in the misalignment causes a higher electric current. As for the effect of misalignment on shaft rotational speed, the rise in the misalignment causes the post-rotational rate to lower.

Abstract

Manufacturing of valves generally uses brass alloy materials and is carried out using a forging process. In this research, the aim is to determine the effect of variations in heating temperature in the valve manufacturing process on the hardness value, microstructure, and shape changes that occur. This research method uses this research method, using an experimental method with temperature variations tested of (300˚, 400˚, and 500 ˚Celsius) with an unchanged compressive force and brass raw material with specifications Cu = 57%. Results of observations that occurred namely Hardness Testing, the lower the heating temperature, the higher the resulting hardness value, which is 69 HRb, 66 HRb, and 59 HRb. When the shape changes, the higher the temperature, the more flash you get, and the lighter the forging force on the forging tool. In the microstructure, as a result of temperature differences, each grain structure characteristic will be different, increasing temperature and forging pressure will change the grain structure.

Abstract

This research is an experimental study conducted to determine the effect of variations in piston diameter on the performance of manual transmission motorbikes. The independent variables in this study are variations in the diameter of the piston with initial conditions 52.5 mm to 53 mm (modification 1) and 53.5 mm (modification 2). Then, the dependent variables in this study are torque, power, and fuel consumption. Torque and power tests were carried out using the dyno test equipment, and fuel consumption testing was done using a measuring cup and calculating the mass of fuel per unit of time; then, the research data was analyzed using quantitative descriptive techniques. In theory, changing the size of the piston affects the compression ratio, which in turn affects the vehicle's performance. After the research, it is known that there is an effect of variation in piston diameter on torque, power, and fuel consumption, where the highest torque is achieved in the use of a modified piston on 53.5 mm by 12.49%, then the highest power is achieved by 7.02%, and the highest fuel consumption is achieved by 17.15%.
