Abstrak. Cakram merupakan salah satu komponen utama pada sistem rem cakram sepeda motor yang berfungsi untuk memperlambat laju putaran roda sepeda motor. Cakram sepeda motor memiliki model pola lubang yang bervariasi jumlah dan bentuknya. Penelitian ini bertujuan untuk menganalisis tegangan maksimum variasi model cakram dan menginvenstigasi potensi area cakram akan retak. Metode penelitian dilakukan dengan pendekatan reverse engineering menggunakan metode elemen hingga. Pengujian dilakukan dengan mensimulasikan cakram pada kondisi statis dengan tekanan sebesar 1.4 MPa dan transien dengan kecepatan putaran cakram sebesar 12 rad/s menggunakan perangkat lunak Ansys Workbench R2 2021 Student Version. Hasil penelitian menunjukkan tegangan maksimum terendah pada cakram Model 1 yaitu sebesar 3.1362 MPa (simulasi statis) dan 507.91 MPa (simulasi transien). Selain itu, visualisasi distribusi tegangan hasil simulasi menunjukkan potensi resiko terendah cakram akan mengalami retak yaitu pada cakram Model 1.

The CC-201-type U18C locomotives are widely used for public transportation in Indonesia. Like other modes of transportation or vehicles, the body's design is an important factor to consider because it influences the aerodynamic capabilities of the vehicle. The study aims to analyze the effect of variations in the design angle of the CC-201 type U18C locomotive body on the coefficient of drag and aerodynamics. The method used in this research is CFD simulation using CAE-based engineering software, Ansys Fluent R2 2022. CFD simulations were performed on locomotive body designs with angle variations of 90°, 135°, and 150° using the same boundary condition parameters. The results show that the locomotive body design with the 60° variation has the smallest drag coefficient value of 0.51076379. The study conclusion explains that changing the angle of 150 degrees at the top of the GE U18C-type locomotive body has a significant effect on lowering the value of the drag coefficient by up to 29%.

The chassis is a critical structural component in vehicle design, especially in electric vehicle (EV) development aimed at reducing environmental impact. This study analyzes the structural performance of a prototype electric vehicle chassis made from 6061 hollow aluminum using Autodesk Inventor 2019. Three chassis models were designed and tested under a static load of 900 N to compare stress distribution, displacement, and safety factors. All chassis designs had dimensions of 2160 mm × 750 mm × 500 mm with a wall thickness of 2 mm. Simulation results showed that the H-type chassis model performed best, with a von Mises stress of 36.03 MPa, displacement of 4.28 mm, and a safety factor of 7.63. These results indicate that the H-type chassis is structurally safe and suitable for prototype application.
