非线性多转子系统动态特性分析的阻抗匹配法

Dynamic Analysis of Multi-Rotor Systems with Nonlinear Dampers by Using Impedance Matching Method

用阻抗匹配法对非线性弹性支承连接或支承的多转子系统进行动力分析的效果令人满意,计算过程简捷,且能清楚地反映各转子的转速、临界转速和弹性支承的非线性动力参数等与整个系统的动态特性之间的联系。

This paper presents the dynamic analysis of the multi-rotor systems with non-linear dampers by using the impedance matching method and the satisfactory results.The method has the advan- tages of simplicity and flexibility.Upon the dynamic characteristics of the systems,the method can reveal the influence of the rotor spin speeds,critical speeds or dynamic parameters of the non-linear dampers.
