干摩擦作用下贮液器的非线性振动与分岔

Nonlinear Vibration and Bifurcation of the Tank Induced by Dry Friction

研究了干摩擦作用下贮液器的非线性振动，利用非线性振动理论与实验模态分析相结合的方法，求出了该系统的极限环和Ｈｏｐｆ分岔解，分析了干摩擦粘滑系数及搓动速度在非线性振动中的作用。本文的方法和结论对同类非线性振动的研究具有一定的参考价值。

This paper deals with the nonlinear vibration of a tank induced by dry friction. By using the combined methods of the nonlinear vibration theory and the experimental modal analysis,the periodic vibration and the Hopf bifurcation of the system are obtained,and the effects of viscosity slide factor and rub velocity on the nonlinear vibration are analysed .
