摘要

针对湿式多片盘式制动器在制动过程中产生振动噪声的问题,通过引入制动器摩擦片和对偶钢片之间的阻尼和刚度,考虑摩擦片和对偶钢片之间由于时滞引起的微小相对位移以及相对位移所产生摩擦阻力的影响,及制动部件的接触摩擦关系,利用非线性接触运动学,提出了湿式制动器制动噪声分析模型,并用复模态有限元仿真分析去验证这种模型的准确性。结果表明,该模型能够较准确地预测制动系统发生制动噪声的趋势,具有重要的工程意义。

Abstract

Aiming at the problem of the vibration noise in the braking process of wet multi- disc brake,the damping and stiffness between the brake disc friction plate and the steel disk are introduced based on the consideration of the small relative displacement of the brake disc and the friction lining due to time delay,otherwise,the contact friction relations of braking component and their effect also take into consideration. By using the nonlinear contact kinematics,the analysis model of the wet brake noise is proposed and the accuracy of this model is verified by using the complex modal finite element simulation analysis. The results show that this kind of model can predict the brake noise more accurately during braking,and the research has vital importance to practical engineering.
