摘要
建立了一类三自由度含间隙系统的力学模型,用变步长四阶Runge-Kutta法,通过理论分析和数值仿真结合,研究了该系统倍周期分岔、杈式分岔向混沌的演化路径,为实际应用中的三自由度含间隙机械系统的动力学优化提供了理论依据。
A kind of mechanical model of three degree of freedom system with clearance is considered in this paper. Through a combination of theoretical analysis and numerical simulation, the routes from period-doubling bifurcation and branch of bifurca- tion to chaos are investied in suitable parameter by means of variable step-size four-order Runge-Kutta. It provides a theoreti- cal basis in the areas of dynamic optimization on the model of three degree of freedom system with clearance in the actual ap- plication.
