中文摘要：
综合考虑摩擦特征和模态耦合,建立了基于刚柔耦合的矿用自卸车盘式制动器模型,以对其振动进行仿真分析。首次通过直接设置柔性体间的接触,模拟制动器典型制动工况,对其进行瞬态动力学分析。研究结果表明,部件间摩擦因数、部件阻尼对盘式制动器的振动有很大影响;合适的部件阻尼可有效提高制动系统的稳定性。
英文摘要：
With concurrent consideration of friction feature and modal coupling,a model for the disc brake of a mining dump truck is built based on rigid-flexible coupling for the simulation and analysis of its vibration.It is for the first time by directly setting the contact between flexible bodies to simulate the typical braking condition of disk brake and conduct its transient dynamics analysis.The results show that the friction coefficient and the damping of components have significant influence on the vibration of disk brake and appropriate component damping can effectively improve the stability of brake system.
