摘要
利用多体系统动力学技术,借助多体系统动力学软件SIMPACK建立受电弓—接触网耦合仿真试验平台。通过仿真试验平台对受电弓模态进行了分析,同时研究了受电弓参数对弓网动态特性的影响。系统研究受电弓—接触网系统的目的在于优化其结构及悬挂参数,以改善弓网受流特性,设计最佳性能的受电弓。
By using the multibody system dynamics technology and SIMPACK software, the simulation platform of the pantograph-- catenary coupling system was established in the design procedure of high-speed pantograph. Modal analysis of pantograph was researched, and the response of contact force and vibration of the pantograph-catenary system under different running speed was calculat- ed. Research on pantograph-catenary system was to reach optimum design purpose o~ pantograph structure and suspension parameters, thus improve the current collecting quality, so it has a guidance meaning for the design of pantograph. Application of virtual prototy- ping in research on pantograph-catenary system accelerates the design speed, and reduces the design cost and shortens developing time of product.
