| 摘 要： | 采用有限元分析方法,建立桥上Rheda 2000无砟轨道轨下基础三维有限元模型,进行动力学的模态分析,获得了轨下结构前十阶自振频率和主振型，分析了不同桥梁弹性模量对自振频率的影响。结果表明，弹性模量越大，结构自振频率越大。

| Abstract: | 3D finite element model of rail foundation of Rheda 2000 ballastless track on bridge is established through finite element analysis to conduct dynamic modal analysis.The first ten natural frequency and main vibration mode of rail foundation are obtained.The influence of elastic modulus on natural frequency of different bridges is also analyzed.It is indicated that larger elastic modulus causes higher natural frequency. |
