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.

Abstract:

Based on the multibody system dynamics and the finite element method,a new co-simulation method for the coupling vibration of a vehicle-bridge system was proposed.By using the finite element substructure method,a dynamic analysis model for a long-span continuous beam bridge,Bahe super-long bridge on Zhengzhou-Xi’an passenger dedicated railway,was established,and the natural vibration properties of this bridge were analyzed.A whole vehicle model was set up with the multibody system dynamics.Then the co-simulation of two subsystems(vehicle and bridge) was performed by interfacing data exchange at discrete communication points,and the coupling vibration simulation was achieved.The research results show that the co-simulation is feasible and its realization provides a new strategy for the research on the coupling vibration.

Keywords: coupling vibration of vehicle and bridge   co-simulation   multibody system dynamics   finite element method
