摘　　要：研究了电气化列车受电弓—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。提出了一种基于Newmark算法的受电弓—接触网系统模型,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。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。This paper studied the optimization modeling of electric train pantograph-catenary structure system, and analyzed the effect of contact wire sag on bow net flow. The traditional bow net model uses modal superposition method to solve, the process is tedious, and easily causing truncation errors. This paper presented a system model of bow-catenary based on the Newmark algorithm. The model regarded catenary as a stiffness changing system, and was simultaneous with the pantograph system. The bow net movement equations were given, and the Newmark method was used to direct integral to solve. Using ANSYS software to form the simulation model of bow net, analyzing the effect of sag on the quality of the bow net by flow. The simulation results can satisfy the actual requirements, which provides a reference for the design of the catenary.
