刚性接触网的不平顺分析

研究目的:刚性接触网的不平顺会激发受电弓和刚性接触网之间的有害振动,破坏受流,影响行车安全。在我国对刚性接触悬挂不平顺的研究刚刚起步,所以对刚性接触网不平顺进行分析是十分必要的。研究方法:对刚性悬挂不平顺进行数值模拟分析以及推导受电弓与接触网系统的计算模型。研究结果:推导出了刚性接触悬挂的受流性能由2个方面决定,一是受电弓的受流特性,二是刚性接触悬挂的接触面的不平顺值。研究结论:刚性接触悬挂的不平顺是研究受电弓与刚性接触网系统振动的基础,减少刚性接触悬挂的不平顺,受流质量将得到提高。

Unevenness Analysis of Overhead Rigid Suspension Catenary

Research purposes: The unevenness of Overhead Rigid Suspension arises the bad vibration between the pantograph and rigid suspension,which can spoil the current collection and endanger the running safety.The study is beginning in our country,so the analysis on unevenness of Overhead Rigid Suspension is necessary.Research methods:The numerical simulation analysis,pantograph and catenary numeration model are used to unevenness of Overhead Rigid Suspension.Research results:The current collection performance depends on its pantograph compliance characteristics and unevenness of its contact surface.Research conclusions:The unevenness of Overhead Rigid Suspension is the basis of study on vibration of pantograph with rigid suspension,reducing the unevenness,and the current collection quality will be promoted.
