Simulation of High-Speed Pantograph Dynamic Performance Based on Finite Element Model and Aerodynamic Pantograph Model

  • 摘要: 建立了接触网和受电弓子系统的有限元模型和空气动力学模型,采用MSC-Marc及STAR-CD软件,研究受电弓动态受流性能和空气动力学性能.通过接触实现2个子系统耦合,对弓网进行动态仿真;通过高速受电弓三维模型,对受电弓高速空气动力学性能进行仿真.仿真结果表明:简单链型悬挂比弹性链型悬挂接触线动态抬升量和平均接触压力均小,在速度250 km/h时,气流对受电弓产生的抬升力约为12 N,空气阻力为550 N.
