Coupling Vibration Simulation of Long-Span Continuous Beam Bridge on Passenger Dedicated Railway

  • 摘要: 提出用多体系统动力学与有限元法相结合的联合模拟技术进行车桥耦合振动仿真分析.以郑州—西安客运专线灞河特大桥的一大跨连续梁桥为研究对象,采用有限元子结构技术建立桥梁动力分析模型,对桥梁自振特性进行分析,采用多体系统动力学程序建立完整的车辆空间模型,然后将桥梁和车辆2个子系统在轮轨接触面离散的信息点上进行数据交换,从而实现车桥耦合振动仿真.研究结果表明,联合模拟技术是可行的,为车桥耦合振动的研究提供了一种新的有效途径.
