用变步长法研究电力机车蛇形振动
Dynamic Analysis of the Locomotive Crawl Vibration
摘要
Abstract
Suppose we view a locomotive as a whole system,the space configuration of each locomotive is described by a 17-freedomed in horizon surface.Taking into account the elastic supporting of first and second system,hanging equipment and resistance characteristic,a space vibration model of four-axis bogie vehicle crawl vibration is presented.The characteristic root of the model is calculated.The stability of vehicle crawl vibration and critical velocity is researched.The result is that increasing vertical and horizontal stiffness and resistance of every wheel can decrease crawl vibration of bogies and carriages.And the optimization parameters are given.The improvements lie in using electromagnetic or crawl vibration absorber to replace hydraulic pressure vibration one and using awl spring to replace old pillar one.关键词
