摘要
Abstract
Vibration shock system with shock absorber is studied to establish the vibration model.The Runge-Kutta method is applied to solve the equations of motion,Matlab simulation is conducted to obtain the bifurcation diagram and Poincare map of the system and the path from periodic bifurcation and hopf bifurcation to chaotic motion and the influence of the shock absorber parameters on the dynamical behavior of the system is studied.The results show that the system has complex dynamics such as bifurcation,general period and chaos when parameter changes,and bifurcation diagram chaotic region increases with the increase of nonlinear shock absorber stiffness.关键词
