摘要
建立了多轴转向架曲线，通过力学模型，并对侧向力及数学方程各阶导数进行了分析和讨论，找到了方程根所在范围和函数的变化规律，提出了一种简单可靠的数值解法。计算结果表明，这种方法不仅能求解任意轴数和任意轴距的机车车辆在各种速度和曲线半径下的小半径曲线通过问题，而且比各种传统方法精确、迅速。
A mechanic model of multi-axes truck curving is obataind.By the analysis of lat-eral force and first and second derivatives in the mathematic equation,the existing range ofthe equation root and the varying law of the function are fotind,and a method of numericalcomputation is proposed,calculation results show that the method can be used to solve theproblems of small radius curing of railway vehicles with arbitrary number of axle and anyaxle- base under different vehicle velocity more accurately and quickly than using the tradi-tional methods.
