| 摘 要： | 根据列车-轨道系统运动的特点,提出了适合该问题动力学分析的新型车辆单元和轨道单元,运用有限元方法和Lagrange方程,推导了两种单元的刚度矩阵、质量矩阵和阻尼矩阵。整个列车-轨道系统只需离散成车辆单元和轨道单元,其中轨道系统离散成轨道单元,一节车辆离散成一个车辆单元。该模型具有程序编制容易、计算效率高的特点。作为应用实例,给出单轮通过和考虑轨道完全平顺和具有随机不平顺条件下整车通过时车辆和轨道动力响应分析的二个算例。

| Abstract: | Based on kinetic characteristics of vehicle-track system,new types of vehicle and track elements were presented.Stiffness matrix,mass matrix and damping matrix of these two kinds of elements were deduced by means of finite element method and Lagrange equation.The integral vehicle-track system were discreted into vehicle elements and track elements.The track system was seperated into track elements and each car is taken as a vehicle element.The model has advantages of convenience for programming and high eff... |
