摘　　要：针对铁道客车通过最小反向曲线时,车钩偏移角的校核问题,计算推导出客车在TB/T 2218—2010《铁道客车通过最小半径曲线试验》规定的夹一段直线反向定圆平面曲线上运行时,车钩最大偏移角出现的位置区间和计算方法。以YW25G型客车为例计算车钩最大偏移角,介绍利用Excel电子表格软件求解车钩最大偏移角的方法,计算结果与采用UGS NX三维设计软件草图模块求出的结果一致。In terms of issues that checking the deflection angle of coupler when the railway passenger car crosses the minimum reversed curve,the position range and method of the maximum deflection angle of coupler are introduced in this article,with passenger car crossing the plane curve which clamping a straight line in between specified in TB/T 2218—2010 Tests on railway passenger car negotiating minimum radius curves.Taking YW25G passenger car as an ex ample to calculate the maximum deflection angle of coupler,excel spreadsheet leads to solve solution of the maximum deflection angle of coupler.The results are consistent with that obtained by the sketch module of UGS NX 3D design software.
