摘要
Abstract
Based on the duffing oscillator,this paper introduced and analyzed a single degree of freedom and multiple degrees of freedom nonlinear frame structure system models.With dynamic simulation and calculation process by using the Simulink,time history curve,phase plan,Poincare section and power spectrum diagram of the system were obtained.Chaotic dynamic characteristics of the nonlinear frame structure systemswere analyzed and described comprehensively.关键词
