摘要
本文对高速运行接触网-受电弓系统动态受流特性进行了仿真研究,建立了以连续质点表示的接触悬挂的物理模型和相应的数学模型,应用计算机仿真方法,仿真在不同运行速度下弓线间接触压力、受电弓运行轨迹等动态特性,并得出相应结论,同时提出改善高速受流性能的方法及途径。
In this paper, the physical as well as the correspondingmathematical models expressed in terms of successive particles are setup, based on emulation researches on the dynamic current-carryingcharacteristics of the pantograph--catenary contaet system on high speedrailway lines. Dynamic features of the contact force between the panto-graph and the catenary and the locus of the pantograph under high--speedconditions are emulated with the help of a computer. Based on the results ofabove analyses, methods are put forward to improve the current--carryingperformances under high-speed conditions.
