摘要
通过数值分析获得冲击消振系统典型的稳定周期响应相轨图,在相轨图中直接观察倍周期分叉,并在庞加莱(Poincare)截面中显示了该振冲系统的混沌运动性质。
The stable periodic response of an impact-damping system is obtained by using numerical analysis on the base of reference. The double-period bifurcation is observed directly in the phase diageam. The characteristics of chaotic motion of the system are revealed in the Poincare section.
