| 摘 要： | 从空气动力学角度出发,分析高速弓网受流稳定性。利用三维建模软件UG,建立了高速受电弓的几何模型,将受电弓的几何模型导入流体力学计算软件STAR-CCM＋,采用紊流模型对受电弓在开放空间的空气动力学性能进行了仿真,研究了高速350km/h下风阻对弓网之间抬升力、受电弓弓头和杆件的影响情况,为进一步研究高速受电弓参数和受流性能提供了仿真手段和理论研究基础。

| Abstract: | This paper which beginning with the point of aerodynamic aim to improve the aerodynamic performance and stability of interaction of Pantograph-catenary. First, use 3D modeling software UG to establish the geometry model of high-speed pantograph. Then import pantograph geomantic model into CFD software STAR-CCM+, and simulate aerodynamic performance of pantograph in open area using turbulence model. Furthermore, discuss the effect of Pantograph-catenary lift force, resistance of pantograph head and arm cause... |
