摘　　要：本文用谱分析方法，分析和计算了机车在直线轨道上匀速运行时对轨道横向随机不平顺输入的动力响应，计及了轨道的横向弹性及轮轨间的非线性几何关系。在计算中采用统计线性化方法和迭化法，将结果与线性情况作了比较。he spectral analysis is used to analyse and calculate the dynamic response of a locomotive running at constant speed to random lateral rail irregularities on an elastic tangent track with nonlinear wheel-rail geometric relationship.Statistical linearization and iteration methods are used in the calculation,The results are compared with those of linear problem.
