摘　　要：为了提高盘式制动器的制动稳定性,获得其最优结构参数,建立了盘式制动器有限元模型进行约束模态分析,得到了各零件前6阶的固有频率和振型,结果表明,摩擦盘的第3阶固有频率和卡钳的第2阶固有频率较接近,可能引起系统的共振;采用优化算法对摩擦盘的结构尺寸进行了协同优化设计,优化结果在一定程度上起到了降低系统产生共振的可能,提高了盘式制动器的制动性能。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.
