以模态机械阻抗法分析电力机车的振动

The Vibratial Analysis of Electro-trion with the Model Mechanical Impedance Method

本文以电力机车提速后振动加剧为客观背景,采用一种新的振动研究方法:模态机械阻抗综合法,研究弹性体兼容刚体的复杂机械系统振动问题,并考虑脉流电机的激振力作用,运用MATLAB语言,编写计算程序,得到各隔振器安装点的振级落差及各点的振动响应图线,为电力机车结构设计提供了重要的依据。

The paper according to objective background after promote speed and vibration acute. It puts forward a kind of new vibratial research method： Model mechanical imdepance synthesis method, the method adopt of elastic-body includes rigidbody complex mechanical system, and considering impulse motor incentive force effect, application MATLAB language, write out compute program, getting isolations grade decrease distance and vibration response figure, these supply important dates for electro-trion structure design.
