Coupling Vibration of Vehicle-Bridge System

  • 摘要: 通过用正弦波形模拟桥面的不平和考虑移动车辆-桥梁间的相互作用,在Euler-Bernoulli梁理论的基础上建立了一种车桥系统的耦合振动模型.利用模态分析法和Runge-Kutta法对模型进行数值求解,获得了车桥系统耦合振动的动态响应和共振曲线.发现车桥耦合振动的共振曲线中存在两个共振区域,一个反映主共振而另一个反映次共振.讨论了桥面不平、桥梁振型和车辆间的相互作用对系统振动的影响.数值结果表明,这些参数对系统振动的影响很大,桥面不平和振型对车桥系统耦合振动的影响不能忽略,设计车速应该远离临界车速.
