摘　　要：通过对一客车车辆的稳态曲线通过计算，采用改进了的Ｎｅｗｔｏｎ－Ｒａｐｈｓｏｎ法，通过逐步曲线曲率逼近法求得对于一系列曲线半径的稳态解，使机车车辆非线性曲线稳态解问题获得准绝对的整体收敛性；还可一次性获得对一系列曲线半径的稳态通过性能指标。A curvature approaching method is cited for steady-state curving of railway vehicles. According to a calculation of a passenger vchicle, the result shows that the method is very effective for converging. In addition, in order for the optimization of railway vehicle design, this method makes us easy to obtain a single index to evaluate the curving ability for curves with a range of radii.
