高速电气化铁路正在世界上迅速发展,我国也在规划、筹建准高速及高速铁路。实践证明:弓网关系及动态受流是当代影响列车提高速度的关键技术问题。本文结合我国国情,对高速受流的评价技术指标、高速动态受流特性以及影响高速受流的因素进行了深入系统的分析与研究,建立了相应的动态物理模型及数学模型,同时利用计算机仿真技术探讨了高速运行时的弓网关系、悬挂方式及其技术参数,得到了有益的分析结论。

Highspeed electrical railway is being developed rapidly. China is now planning to construct quasihighspeed and highspeed railways. Practical evidences prove that the pantograph-catenary relationship and dynamic current-carrying are the key techniques in effecting the increase of train speed. Concerning the realistic condition of China, this paper makes systematic analyses and researches on technique indices of highspeed current-carrying evaluation features of highspeed dynamic current-carrying and factors that affect highspeed current-carrying. Relevant dynamic physical models and mathematical models are established. Meanwhile, by using the computer simulation technique, we inquires into the hanging styles and pantograph-catenary relationship of highspeed, and draw a beneficial analytical conclusion.
