| 摘 要： | 基于非线性有限元理论,建立了京津城际高速铁路弓网动态系统的有限元模型,采用欧拉-伯努利直梁模拟接触网各部件,采用铰链和非线性弹簧相互耦合模拟受电弓,借助MARC软件,对京津城际高速铁路弓网受流情况进行了动态仿真,并利用MARC的后处理功能显示弓网运动过程中的三维动态情况.计算得到了京津城际弓网动态系统的平均接触压力为160.68 N,接触点动态抬升量变化范围为28.5～87.0 mm.与西门子公司提供的仿真结果及京津城际现场的测试结果比较表明:有限元模型是正确和有效的,京津城际弓网动态系统具有良好的动态受流质量.

| Abstract: | Based on the nonlinear finite element theory(FEM),a finite element model of the pantograph-catenary dynamic system of Beijing-Tianjin intercity high-speed railway was established,in which nonlinear flexible catenary was modelled by using Euler-Bernoulli flexible beam and the pantograph was modelled by using hinge and nonlinear springs. The dynamic current-collecting performance of the system was simulated by using MARC software,and using whose post-processing function,the three dimensional dynamic performan... |
