非线性框架结构SH-CSU系统的混沌动力特性
haotic Dynamic Characteristics of Nonlinear Frame Structure Based on SH-CSU model
本文在分析单自由度以及多自由度非线性框架结构体系的动力方程后，以滑移滞后模型（SH-CSU模型）作为恢复力依据，借助于Simulink软件对系统进行动态模拟仿真和计算处理，得出系统的时程曲线图、相平面图、Poincare截面图和功率谱图，综合分析并直观表明非线性框架系统在一定条件下所表现出混沌动力特性。
Based on the SH-CSU model, this paper introduced and analyzed single degree of freedom and multiple degrees of freedom nonlinear frame structure system model. After dynamic simulation and calculation process by Simulink, time history curve, phase plan, Poincare section and power spectrum diagram of the system were drawn out. The chaotic dynamic characteristics of the nonlinear frame structure system is analyzed and described comprehensively.
