含间隙及摩擦的振动系统动力学分析
Dynamical Analysis of Vibration System with Clearance and Friction
摘要
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 nonsmooth 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.关键词
