Optimization Design of Disc Brake Based on Collaborative Technology

In order to improve the brake stability of the disc brake and obtain the optimal structure parameters,a finite element model of the disc brake was established for constraint modal analysis.The first six order natural frequency and vibration model of each part were obtained.The results showed that the third order natural frequency of the friction disk and the second order natural frequency of the caliper are close,may cause resonance of the system.Then,the structure and size of the friction disc were optimized by the collaborative optimization algorithm.The optimization results reduce the probability of the resonance,and improve the braking performance of disc brakes.
