摘要
利用MLP方法对一类耦合的强非线性系统进行研究,通过参数变换,摄动展开和逐个求解摄动方程,获得了系统的近似解析解。绘制了系统的时间历程曲线和相轨线。该求解方法可以推广应用到其它的多自由度强非线性系统。
Using MLP method, a class of coupling nonlinear system was studied. Through the transformation of parameters, and each perturbation method for perturbation equation, the approximate analytical solution of the system was obtained. The time course of the curve and the corresponding trajectory were drawn. The solution can be applied to many other freedom nonlinear systems.
