The brake is the key mechanism of automobile braking system, which makes the vehicle reach the expected driving state by outputting braking force to the wheel. SolidWorks was used to model the pneumatic disc brake of EQ1180GEVJ new energy commercial vehicle. The finite element software ANSYS workbench was used to conduct the finite element analysis of the brake disc, brake clamp and bracket, and the stress cloud diagram under the braking condition, as well as the first 10 natural frequencies and the main vibration pattern diagram were obtained. The results show that the maximum deformation of the brake disc is in the lower position on both sides of the brake disc, and the maximum stress is in the position connected with the wheel hub. The maximum stress of the brake clamp is at the connection between the connecting arm and the brake chamber. The maximum stress of the support is at the connection between the support and the suspension. The first ten natural frequencies of the three parts are between 240Hz and 3000Hz. By analysing the mode, we can obtain the position where the mode which is prone to sudden vibration frequency change and the system may generate the maximum vibration amplitude when resonance occurs. The results provide some references for further optimization of disc brake.
