摘要
本文通过研究点映射的不动点稳定性,分析了车辆非线性系统的周期运动稳定性。结合实例,采用数值积分方法,得到非线性车辆系统的运动极限环,讨论其稳定性,分析了极限环圈的稳定域,并就车辆系统非线性运动分叉现象进行了探讨。
y studing the stability of the stationary point obtained by reflection,the periodic motion stability of railway vehicle nonlinear system are analysed in this paper. Using the value integration method,the limit cycle of the nonlinear vehicle system are obtained. The stability area of the limit cycle are analysed, and the bifurcation phenomenon are discussed as well.
