Abstract

This paper analyses the braking noise by establishing the shaft disc brake finite element model using ANSYS Workbench platform. Through a comprehensive investigation of influencing factors such as the friction coefficient of the brake disc, brake pressure, shape of the brake friction block and their arrangement, it is found that the friction coefficient has a great influence on the brake noise. Besides, the simulation results also uncover that the influence of brake pressure on brake noise depends on whether the brake pressure reaches a specific critical value. Lastly, through extensive simulations, it shows that the braking noise level is distinct for different shapes and arrangements of the brake pads.
