摘　　要：在建立受电弓 /接触网系统仿真计算模型 ,进行受电弓在接触网下运行动态仿真计算的基础上 ,探讨接触网弛度对弓网接触受流的影响 ,研究合理弛度的设计。本文提出接触线表面不平顺的新概念 ,研究因接触线表面不平顺对接触压力的影响 ,并就如何通过改变受电弓的动力参数来减小接触线表面不平顺对受流的影响进行分析。Based on setting up the simulation model of pantograph/catenary system, and simulating the dynamic behavior of the pantograph running under the catenary, the effect of the contact wire's sag on current feeding is studied, and the reasonableness sag of the contact wire is discussed. A new concept, which called as irregularity of contact wire, is propounded. Its influence on contact force is investigated, and how to reduce the influence of contact wire's irregularity upon the contact state by modifying the pantograph's dynamics parameters is analyzed.
