摘要

干摩擦结构广泛存在于机械系统中，由此引起的振动行为属于典型的非光滑动力学研究范畴。通过将含干摩擦非线性振动系统看作一分段线性系统，提出了求解各粘滑状态阶段解析解的方法，并以两自由度干摩擦振动系统的力学模型为例进行了数值模拟，进而分析了由干摩擦导致的粘滑振动行为。

Abstract

Dry friction structures existing in many mechanical systems, the resulting vibration behavior which is a typical non-smooth dynamical scope of the study. The paper will nonlinear vibration system with dry friction as a piecewise linear systems, the method of solving the analytical solution for all stick-slip state of phase has been proposed, the model of two degrees of freedom dry friction vibration system as an example, which dynamic responses are analyzed by numerical simulation and stick-slip vibration induced by dry friction is discussed.
