Analysis and optimization of vibration noise of disc brakes based on Workbench

  • Received Date: 2017-10-12
  • In order to solve the problem of loud noise of automobile braking, taking a certain electric vehicle disc brake was the research object, a 3D model of the brake was established by using Soildworks software, and the model was analyzed by complex modal analysis on Workbench platform, and the distribution of vibration and noise during braking was obtained. The structure of the brake pad was optimized by means of chamfered, digging grooves in the middle and riveting the shim in the steel back. Finally, the NVH performance test of the brake before and after the improvement carried out using the Dynamometer-GIANT 8600 inertia test bench. The experimental results showed that the lower the friction coefficient,the smaller the real part value of the complex eigenvalue of the brake, and more stable the system. The improved brake could effectively reduce the frequency of the unstable modes of the system, so that the braking noise of the vehicle was significantly reduced at low speed, and the NVH performance of the brake was significantly improved.
