不同受电弓对刚性接触网锚段关节的适应性研究

Studies on Adaptability of Different Pantographs to Rigid Catenary Overlap Section

对于采用刚性接触网的城轨交通线路,随着其运营速度不断提高,对弓网动态性能要求越来越高。锚段关节是刚性接触网的关键区段,有必要对不同受电弓在高速通过锚段关节时的弓网动态性能进行研究。本文以北京地铁大兴机场线为例,利用有限元法建立3种型号受电弓与刚性接触网的弓网仿真模型,分析比较3种型号受电弓以160~220km/h速度通过锚段关节时的弓网动态性能,为研发更高速度等级的受电弓与刚性接触网系统提供技术参考。

Along with the constant speed increase of urban rail transit line adopted with rigid catenary,the requirements for dynamic performance of pantograph-catenary system are getting more higher and higher.The overlap section is the key section on rigid catenary,so it is necessary to study the dynamic performance of pantograph-catenary system when different pantographs pass through the overlap section at a high speed.The paper,taking with the Beijing Daxing Airport Line as an example,on the basis of pantograph-catenary simulation model for 3 types of pantographs by use of finite element method,analyzes and compares the dynamic performance parameters of pantograph-catenary system when three models of pantographs passing through the overlap section at a speed of 160~220 km/h,it is able to provide the technical experience for development of pantograph-rigid catenary system with higher speed level.
