时速160公里刚性接触网定位点导高偏差研究

Study on Deviation of Contact Wire Height at Registration Point of Rigid OCS under 160 km/h

列车受电弓高速运行时,弓网动态性能的优劣直接影响弓网系统的运行安全性。刚性接触网定位点导高存在偏差会对弓网动态性能产生显著影响。本文利用弓网仿真模型对时速160 km刚性接触网不同跨距时的定位点导高偏差进行研究,基于弓网动态性能评价指标分析比较不同仿真工况的计算结果,得出时速160 km刚性接触网定位点导高偏差允许值,为今后类似工程实施提供参考。

The advantages and disadvantages of the dynamic performance of pantograph-catenary will directly affect the operation safety of the rigid OCS when the pantograph of the train is running in a high speed.The contact wire height deviation at the registration point will affect dramatically the dynamic performance of the pantograph-catenary.The paper,studies the contact wire deviation at the registration point under different span length under 160 km/h by using the pantograph-catenary simulation model,analyzes and compares the calculation results of the simulation of the different working states,obtains the permissible value of contact wire height deviation at the registration point of rigid OCS under 160 km/h,providing reference for implementation of the similar projects in the future.
