摘　　要：盘式制动啸叫问题依然是车辆领域的一大难题。针对盘式制动尖叫发生的普遍性,简化盘式制动器的模型,基于ABAQUS进行复特征值分析计算,预测出盘式制动器的尖叫频率,并通过结构参数的方法分别分析了制动转速、制动压力、摩擦系数、以及制动盘刚度对制动尖叫的影响。再通过结构优化,通过仿真对比验证这种方法的可行性。最后,通过制动台架试验,得到实验中的啸叫频率,从而验证仿真的可行性。本研究的工作有助于理解和揭示汽车盘式制动器制动尖叫的产生机理。Disc brake noise is still a big problem in the vehicle field.First,considering the universality of disc brake squeal,the model of disc brake is simplified,the complex eigenvalue analysis is calculated bused on ABAQUS,the squeal frequency of the disc brake is predicted,and the method of structural parameters is used to analyze the brake speed,brake pressure,friction coefficient,and the influence on brake squeal.Second,optimizes the structure and verifying the feasibility of this method by simulation comparison.Finally,the squeal frequency is got in the experiment by the brake test bench,which verifies the feasibility of the simulation.h is helpful to understand and reveal the generation mechanism of disc braking scream by this study.
