曲线区段接触线拉出值的确定

分析了曲线区段接触线拉出值超标的原因,提出了影响拉出值的各主要因素的计算式,并在忽略了一些影响列车振动的次要因素的条件下,得到了曲线区段弓-网位置的动态变化情况,进而讨论了接触线拉出值的选取原则。

The causations of zigzag value over-bound of curved contact line are analyzed, and formulas of major zigzag effecting factors are proposed as well. At the same time, with neglecting some minor factors of vehicle vibration, dynamic position changing of pantograph and catenary of curved contact line is therefore available. Moreover, the principle of selecting zigzag of contact line is discussed also.
