弓网耦合动力学模型仿真及接触网不平顺分析

通过建立弓网耦合系统模型,对列车在不同速度下的弓网接触压力进行了仿真,研究和讨论了接触压力和接触线抬升量的变化趋势。针对接触网的不平顺情况,论文提出采用谱分析方法研究接触网的不平顺性,具体采用功率谱密度来分析影响弓网受流的波长成分。仿真结果表明,该方法具有较好的直观性和有效性。

Pantograph and Overhead Contact Line Coupling Dynamic Model Simulation and Analysis of Imbalance of Overhead Contact Line

By modeling of pantograph-catenary, this article simulates contact force of pantograph-catenary when the train is in different speed, and researches and discusses the variation tendency of comact force and contact wire lifting value. In view of irregularity of catenary, this article proposes spectral analysis method to research catenary irregularity, concretely, this article analyses wavelength that destroy quality of pantograph-catenary current collection in power spectral density. The result indicates that the method is intuitionistic and effectual.
