摘要

本文针对某型高速动车组车辆地板高频振动过大的问题，研究车底牵引变流器振动及内部悬挂隔振的影响。对牵引变流器进行了装车和车间振动试验，对其振动特性及安装在变压器与变流器柜体之间隔振器的隔振性能进行了理论和试验评估，提出了优化隔振器参数降低变流器振动的措施，并利用有限元和多体动力学软件对优化前、后的隔振效果进行了仿真对比计算。结果表明采用优化后的隔振器参数可大幅降低该牵引变流器的振动，且可避免共振风险。

Abstract

The vibration of a certain type of high-speed EMU traction converter and its internal suspension vibration isolator were studied,aiming at the high frequency vibration on the EMU vehicle floor. Loading and workshop vibration tests were carried out,theoretical and experimental analyses were performed to evaluate the vibration characteristics of the traction converter and the vibration isolation performance of the isolator mounted between transformer and converter cabinet. A method to reduce the vibration of this type of converter was proposed by optimizing the parameters of the isolator. A comparative simulation analysis on the isolation effects before and after optimization was carried out by using finite element and multi-body dynamics softwares. The results indicate that by optimizing the parameters of vibration isolator,the vibration of this type of traction converter can be significantly reduced and resonance does not occur.
