摘要
本文分别利用Lyapunov指数方法和特征值方法,对摸拟地震过程的线性粘弹性动力学模型的稳定性进行了分析,并讨论了粘性力在地形变动力学系统演化过程中的作用,采用Runge-Kutta格式的Merson修改方法模拟了在不同粘性系数时线性和非线性动力学系统的演化过程,得出了一些有意义的结论和认识。
Using Lyapunov exponent method and characteristic value method respectively,we dis-cuss and analyse the stability of linear viscoelastic dynamical system of deformation in thispaper.Both linear and nonlinear evolution processes of dynamical system of deformation areimitated by computer with Runge-Kutta-Merson method.Some conclusions are physics basisin understanding the process of earthquake deformation.
