摘要
为探究曲线区段弓网系统的动力学特性,利用有限元方法对曲线区段线路条件下弓网系统空间位置进行数学解析,建立弓网系统仿真模型,并对不同行车速度、曲线半径、接触网拉出值下的曲线区段弓网系统进行非线性瞬态分析。结果表明:曲线区段行车速度越高、曲线半径越小,弓网接触力波动越剧烈;接触网相邻定位点拉出值设置大小差异越大,弓网接触力的波动越大,弓网系统稳定性越差。
In order to explore the dynamic characteristics of the pantograph-catenary system in curve sections,the finite element method is used to mathematically analyze the spatial position of the pantograph-catenary system under curve section,establish a simulation model of the pantograph-catenary system,and conduct nonlinear transient analysis of the pantograph-catenary system in curve sections under different running speeds,curve radii,and stagger values of contact wire.The results show that the higher the running speed and the smaller the curve radius in the curved section,the more severe the fluctuation of the contact force between pantograph-catenary.The greater the difference in the stagger values of adjacent registration points of the overhead contact system,the greater the fluctuation of the contact force between the pantograph-catenary,and the poorer the stability of the pantograph-catenary system.
