Abstract

Brake pads are a vital factor in the braking cycle and advanced studies should be given on the coefficient of friction, wear and its stages. Through finite element method (FEM) simulation is one of many programs to determine the phenomena that occur in these components. In this study, the rear brake force (drum) of a motorcycle is simulated. The method applied is friction modeling of the braking process. This analysis is implemented with a simulation program in the form of 3D modeling using the finite element method (FEM). The brake pads are made of composite materials (coconut shell, aluminum and epoxy resin). Since the braking process involves variations in pressure and torque forces, the analysis is carried out using static analysis to obtain deformation and von misses results, and dynamically the results of frictional stress, sliding distance and pressure to obtain friction coefficient values. The changes were made by applying speed at a constant load. The simulation results show that at 300 rpm with a given load of 2kg, the stress and friction coefficient values that occur are greater than the 400 rpm and 500 rpm variations in the brake lining. The drum stops at 300 rpm and 400 rpm variations in the 2kg load and the drum decelerates in the 500rpm variation.
