摘　　要：刚性接触网是城市轨道交通系统的重要组成部分,其与受电弓相互接触实现电能传输。刚性接触网定位线夹刚度值会对弓网动态性能产生显著影响,进而影响弓网系统的运行安全。本文利用弓网仿真技术对时速120~160 km刚性接触网不同跨距时的定位线夹刚度进行研究,根据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120~160 km刚性接触网定位线夹刚度最优取值,为后续工程实施提供参考。Rigid overhead contact line is an important part of urban rail transit.It contacts with pantograph to achieve the transmission of electrical energy.The stiffness of contact wire clamp of rigid overhead contact line will generate great impact on the dynamic performance of the pantograph and rigid overhead contact line,and further affect the operation safety of the pantograph and rigid overhead contact line.The paper,on the basis of the study on the stiffness of contact wire clamp at different spans of rigid overhead contact line with speed of 120-160 km/h by application of the simulation technology of pantograph and rigid overhead contact line,analyzes the calculation results under simulation of different working conditions in accordance with the assessing index of dynamic performance of pantograph-catenary.The optimized stiffness value of contact wire clamp of rigid overhead contact line under speed of 120-160 km/h is obtained,providing reference for the implementation of subsequent projects.
