接触网支持悬挂系统的动态特性研究

A Research over the Dynamic Characteristics of Catenary Supporting System

以接触网的支持悬挂系统为研究对象 ,采用有限单元法对其进行模态分析 ,从而得到有关支持悬挂系统的固有频率和振型 。

A modal analysis was made of catenary supporting system by finite element method, resulting in natural frequency and vibration mode of the system. An exploration was made of the dynamic characteristics of the system.
