摘要
建立了一类两自由度单边刚性约束碰撞系统的力学模型,通过理论分析和数值仿真结合,推导了系统周期运动的解析解和Poincaré映射,分析了系统周期运动的稳定性及系统在适当参数下发生分岔与混沌的现象,为实际动力学系统优化提供了理论依据。
A kind of mechanical model of two-degree-of-freedom impact system with unilateral rigid constraints is considered in this paper. Through a combination of theoretical analysis and numerical simulation, analytical solution and Poineare map- ping of the periodic motion of the system are deduced, the stability of periodic motion, the phenomenon of bifurcation and cha- os in the proper parameters of the system are analyzed. It provides a theory basis for practical dynamics system optimization.
