高速受电弓-接触网系统动态受流性能的仿真分析

采用了MSC-MARC软件对受电弓-接触网系统的动态受流性能进行了仿真，分别建立了接触网和受电弓两个子系统的有限元模型，通过接触实现了两个子系统的耦合，进行弓网的动态分析．通过仿真，将低速下得到的结果与国外的结果相比较，验证了软件分析结果的正确性．针对高速铁路一种受电弓-接触网的设计参数，对弓网之间的相互作用进行了分析，得到了高速下接触网的动态抬升量，接触压力和离线率，通过参数的调整保证弓网可靠作用达到良好的受流．对高速受电弓与接触网的相互作用进行了大量的仿真并对结果进行分析，为进一步研究高速下受电弓与接触网不同参数的配合奠定了基础．

A Simulation Study on Current Collection of High-Speed Pantograph-Catenary

A novel finite element （FEM） simulation approach on the current collection of high-speed pantograph-catenary is presented in this paper. Based on MSC-MARC simulation platform, the coupled FEM model of the pantograph-catenary system has been established at first, and the interactions of coupled model at normal speed is simulated and compared with the foreign results, which verifies the correctness of this approach. The model takes the high-speed parameters into account and considers the interaction of pantograph-catenary. The results of the simulation include the dynamic uplift of contact wire, contact force and loss of contact force. The good current collection is obtained by modifying the parameters of two subsystems. The further study will optimize the parameter of the pantograph-eatenary system based on the simulation results analysis.
