本文概述受电弓与接触网之间的机械动态仿真研究及其应用的现状,并展望弓网动态仿真技术的发展方向。现有弓网动态仿真的手段主要有全虚拟仿真和半实物半虚拟仿真,弓网仿真模型的建立主要有直接解连续方程法、连续方程离散法和直接离散法。为减小弓网振动,延长设备寿命,弓网仿真将向优化弓网结构、受电弓主动控制、弓网故障识别等方面发展。分析现阶段弓网动态仿真技术中的不足,对未来研究工作提出若干建议。

This paper provided an overview of the research on dynamic simulation between pantograph and catenary and the status of its applications,and looked into the future development of dynamic simulation of pantograph and catenary system.Existing pantograph-catenary dynamic simulation methods mainly include virtual simulation and semi-virtual semi-physical simulation.The establishment of pantograph-catenary simulation model mainly depends on continuous equation direct solution method,continuous equation discrete method and direct discrete method.To reduce vibration and prolong lifespan of pantograph and catenary system,simulation will be further developed in optimizing structure of pantograph and catenary,active control of pantograph,and failure recognition of catenary.Finally,the deficiency in current simulation of pantograph and catenary system was analyzed and some suggestions were proposed for future research.
