摘要

摘要本文描述了一种最小汽车盘式制动器模型的振动机制，该模型可能导致被称为制动噪声、振动和粗糙度(NVH)的不良影响。粘滑摩擦效应是通过物理假设的简化在数学上描述的。由粘滑引起的自激振动和稳定性条件用1自由度机械系统来定义。考虑了负斜率摩擦力的非库仑非线性行为。通过常微分方程的数值解得到响应。

Investigation of Frictional Stick-Slick Effect in Disk Brake NVH

Abstract Paper describes the mechanism of vibration of a minimal automotive disc brake model which can lead to unwanted effects known as brake Noise Vibrations and Harshness (NVH). Stick-slip frictional effects are mathematically described by simplification of physical assumptions. Self-excited vibrations due to stick-slip and also stability conditions are defined using a 1 degree of freedom mechanical system. Non-Coulomb nonlinear behavior of the friction force with negative slope is considered. Response is obtained by the numerical solution of ordinary differential equation.
