摘要

基于高速盘式制动器的简化有限元模型,利用Abaqus进行复特征值仿真分析,对引起制动啸叫的主要影响因素进行研究。仿真结果表明:低速、高压、摩擦因数-速度曲线负斜率和高摩擦因数情况下,发生制动啸叫的可能性较大。通过不同制动速度和压力的制动实验验证了仿真研究结果的正确性。研究将对有效预防和控制制动啸叫具有指导意义。

Abstract

Complex eigenvalue analysis using ABAQUS has been carried out,based on a simplified finite element model of high-speed disc brake system.The critical factors generating brake squeal have been computationally studied and verified by experiments.Simulation results show that,brake squeal more likely to occur under the conditions of low-speed,high pressure,negative μ-υ slope,and high coefficient of friction.The effects of sliding speed and normal contact pressure on the generation of brake squeal have been verified.This study will provide effective guidance in the prevention and control of brake squeal.
