Abstract: The braking system is a very important part of the safe driving of the car, ensuring that the driver can safely control the deceleration and parking of the car. Disc brake is a common type of automotive brake system, its operating characteristics are high speed, high temperature and vibration. The high temperature and vibration of disc brake have great influence on its working performance and directly affect the safety of disc brake. In this paper, through finite element simulation analysis of key parts of disc brake, the first 6 natural frequencies and vibration modes of key parts are obtained, so as to accurately grasp their vibration characteristics, and the corresponding design and analysis of the friction liner structure are carried out. The research results provide a certain theoretical reference for the design of key parts of disc brake.
