【摘要】 本文研究了一端固定一端滑动承受轴向简谐载荷的屈曲梁的非线性响应现象.利用数值模拟分析了其定态特征、基本参数共振和主参数共振的全局分岔过程,得到了系统的倍周期分岔、暂态混沌和混沌运动等复杂动力学行为.更多还原

【Abstract】 In this paper,the nonlinear responses of a clamped-sliding buckled beam to a harmonic axial excitation are investigated.By using numerical simulations,its steady state characters,bifurcation graphs of fundamental parametric resonance and principle parametric resonance are studied.The system’s complicated dynamic behaviors,such as period doubling bifurcations,transient chaos and chaos are obtained.更多还原
