根据随机振动和系统理论，以普通平车为例建立了计算车辆横向振动最大偏移量的数学模型；通过实例计算了超限车横向振动最大偏移量，分析了其影响因素，并验证了模型的可靠性，对于列车提速后的超限货物运输组织工作具有重要的参考价值
According to the theory of random vibration and system, a mathematical model for calculating the maximum lateral displacement of a vehicle is established by taking ordinary flat car as an example. The maximum lateral displacement of overrun vehicle is calculated by an example, and the influencing factors are analyzed. The reliability of the model has an important reference value for the organization of the overloaded cargo transportation after the speeding up of the train
