摘要
对高速铁路轨道结构力学模型中的参数进行了研究，给出了各参数计算公式和取值范围．同时提供了轨道结构各主要部件动力响应特征参数，如轮轨动力系数、自振频率、振动加速度的实测值范围以及关键部位的最大允许值。
Research on parameters of mechanical model for high speed railway truck is performed and the calculated formulas and the value ranges corresponding to these parameters are given in this paper.At the same time, the dynamic response characteristic parameters for the main components of truck structure, such as wheel/rail dynamic coefficients, nature frequencies, vibration accelerations measured on site and their ranges,and allowable maximum values in some key positions, are presented,which can be used to check the computational results byatheoretical model.
