超小半径曲线上城市轨道交通工程车的通行

Urban Rail Transit Workstrain on Minimal Radius Curve

随着65m的超小半径曲线在城市轨道交通中的应用,使工程车在超小半径曲线上的通过能力产生了一些问题。根据超小半径曲线线路实际情况和工程车的技术参数,对工程车通过超小半径曲线进行受力分析与计算,从而得出工程车的理论安全通过速度,并为能顺利通过超小半径曲线的新型工程车设计提供参考。

With the application of small radius curve of 65 m in urban rail transit,the carring capacity of the curve exposed some problems when the workstrain passes.According to the actual situation of small radius curve line and workstrain's technical parameter,the theoretical security through speed could be calculated on the stress analysis and the computation of workstrain through curve,thus providing a the reference for higher capacity of small curve in diesel locomotive's design.
