用模态机械阻抗综合法分析机车振动

Modal Impedance Synthesis Method Applied to Analyzing Vibration of locomotive

本文以列车运行提速后振动加剧的客观事实为背景,以韶山8型(SS8型)电力机车为例,采用模态机械阻抗综合法对振动系统进行分析,建立复杂机械系统多层隔振动系统的动力学模型,计算电力机车系统前6阶固有频率及振型,为进一步动态响应分析提供依据。

This paper deals with the dynamic property of Saosan8(SS8) electric researched that the vibration of the SS8 using setting up a complex dynamic model calculated for the further analysis.
