A Study on Kinematic Envelope of Pantograph for Electrified Railways

良好的弓网系统动态特性是确保电气化铁路可靠运营的关键,受电弓的横向偏移量和上下抬升量是影响弓网耦合安全性的重要参数。本文通过对比分析国内外标准,详细介绍了动态包络线的计算方法,调研收集了国内外铁路动态包络线实测数据,通过弓网系统仿真探讨了影响受电弓动态包络线范围的决定性参数。研究成果可为电气化铁路受电弓动态包络线标准制定提供系统思路。

Good kinematic characteristics of the pantograph-OCS system are the key to ensuring the reliable operation of an electrified railway,and the lateral offset and uplift of pantograph are important parameters affecting the safety of pantograph-OCS coupling.Based on the comparative analysis of standards at home and abroad,in this paper,the calculation method of kinematic envelope is introduced in detail,the measured data of kinematic envelopes of railways at home and abroad are investigated and collected,and the decisive parameters affecting the range of kinematic envelope of pantograph are discussed through pantograph-OCS system simulation.The findings of this paper can provide systematic ideas for the formulation of standards for kinematic envelopes of pantographs for electrified railways.
