摘要
Lyapunov指数是定量描述系统运动状态的重要参数之一.讨论了Lyapunov指数谱的数值计算方法以及它和总时间的关系,利用混沌状态下系统的最大Lyapunov指数大于零的性质预测了非线性隔振系统处于混沌运动状态时两个可变参数的参数区域.
The Lyapunov exponents are ones of the importantparameters for describing quantitatively the system state of motion. The numerical calculation method of the Lyapunov exponential spectrum and its relation with the totaltime are discussed.Subsequently,according to the principle, namely the largest Lyapunov exponent will bepositive if the system is inchaotic motion state, the parameter regions where the system with two or more variableparameters is in chaotic motionare predicted.
