Study on Optimization of Pantograph-catenary Simulation Models for High-speed Rigid OCS

随着刚性接触网线路上列车的运行速度逐步提高,对弓网动态性能的要求也更高,良好的弓网接触力能保证电力机车持续取流。利用弓网仿真技术可以方便高效获取弓网接触力,因此有必要对弓网仿真模型建模方法进行研究,建立高精度弓网仿真模型,获取精确的弓网接触力。本文基于力学理论与有限元理论建立汇流排、悬挂装置、锚段关节等仿真模型,依托北京地铁大兴机场线开展实测对比验证,为探究更高速度等级的受电弓与刚性接触网系统提供理论支撑。

Along with the gradual increase of train running speed on rigid overhead contact line system,the requirements for pantograph-catenary dynamic performance are also higher.Good pantograph-catenary contact force can ensure continuous current collection of electric locomotives.The application of pantograph-catenary simulation technology can facilitate and efficiently obtain the contact force between the pantograph and the catenary.Therefore,it is necessary to study the modeling method for the pantograph-catenary simulation model,establish a high-precision pantograph-catenary simulation model,and obtain accurate contact force between the pantograph and the catenary.On the basis of the mechanical theory and the finite element theory,the paper establishes the simulation models of bus bars,supporting devices and overlap sections.Relying on the Daxing Airport Line of Beijing Metro,the actual measurement comparison verification is carried out to provide theoretical support for the exploration of pantograph and rigid overhead contact line system with higher grade of running speed.
