受电弓整体结构分析对于改进受电弓的设计,提高受电弓的性能,具有重要意义.为保证良好的受流质量,新型高速受电弓大量采用轻型合金材料制作,这可能导致机械强度和刚度的不足.在满足强度与刚度的前提下,最大限度减小受电弓归算质量,以改善弓-网动态性能是受电弓设计的关键问题.文中结合受电弓的开发过程,建立三维仿真模型,利用有限元计算软件Ansys,进行受电弓的强度和刚度校核以及动力特性分析.研究受电弓动力特性的目的在于优化其结构,以控制其模态频率与模态振型,对受电弓的设计具有指导意义.通过对受电弓有限元分析,进行虚拟设计,首次进行高速受电弓的整体结构特性分析.

The finite element analysis of the pantograph is important for improving the design and advancing the capability of the products.In order to ensure better current-receiving quality between pantograph and catenary, the wide use of new alloy materials for high-speed pantograph can also cause the deficiency of the mechanical strength and stiffness.How to ensure sufficient mechanical strength and stiffness but small equivalent quality to improve the dynamic behavior of the pantograph catenary system is a serious problem of the pantograph design.In the design procedure of pantograph, the three-dimensional simulative model of the pantograph was set up to check the strength and rigidity, and study on dynamic property, by use of Ansys.Research on dynamic property is to reach optimum design purpose of pantograph structure parameters and control its natural frequencies and modes, so it has a guidance meaning for the design of pantograph.The virtual design of the pantograph was done by use of the finite element analysis.And the whole structure characteristics of the high-speed pantograph are analyzed for the first time.
