摘　　要：研究电气化铁路受电弓—接触网结构系统优化建模问题,分析了接触线预弛度对弓网受流的影响。传统的弓网模型多采用模态振型叠加法进行求解,过程比较繁琐,且容易引起截断误差。针对上述问题,将接触网看作一个刚度不断变化的系统,与受电弓系统联立,给出了弓网运动方程,并提出采用Newmark方法进行直接积分求解。根据上述方法,使用ANSYS软件建立了弓网仿真模型,分析了预弛度对弓网受流质量的影响。仿真结果能够满足实际要求,可为接触网的设计提供参考。The model optimization and solving of the pantograph - catenary system on electrified railway were researched. And the influence of contact wire pre - sag on current - collecting of pantograph - catenary system was analyzed. In this paper, the motion equations were given, treating the catenary as a system with stiffness changing constantly and combining with the pantograph system. Newmark method was used to solve the equations. According to a- bove method, the simulation model of the pantograph - eatenary system was established with ANSYS software. The influence of the contact wire pre - sag on current - collecting quality of pantograph - catenary system was discussed. The simulation results are in accord with actual requirement, and can provide some reference for the design of cate- nary.
