摘要

摘要: 考虑接触表面工况的差异性，建立一类含两类摩擦及间隙的两自由度碰撞振动系统动力学模型，给出系统在不同运动阶段的判断条件和粘-滑-碰运动行为过渡准则，采用数值仿真方法对系统求解，结合判断条件分析摩擦对系统造成的非光滑运动特性及复杂的动力学行为，同时分析不同摩擦模型对系统动力学特性的影响。结果表明，系统存在瞬时摩擦诱导振动、周期颤振、颤振向粘着过渡及粘-滑-碰之间的转换等摩擦振动现象。

Abstract: The dynamics model of a two-DOF vibration system with two kinds of friction which is considered by the differences of working condition of contact surface and clearance is established. The system in different stages of exercise judgment and stick-slip-impact behavior transition rules are given, then using the numerical simulation method to solve the differential equations of system, combined with the judgment condition to analyze the non-smooth movement characteristics caused by the friction and the complex dynamic behavior, and the influence of different friction models on the dynamics of the system. The results show that the system exists the friction vibration phenomenon including the instantaneous friction induced vibration, period flutter, flutter transition to sticking and among the conversion of stick-slip-impact.
