摘要

以大型通用有限元计算软件ANSYS为计算与开发平台,利用其自有的APDL语言进行二次开发,采用移动质量和弹簧对车辆进行模拟,采用单元生死的方法对车桥耦合振动方法进行探讨,可建立不同类型车辆运行在桥上时整个车桥时变系统的质量矩阵、刚度矩阵、阻尼矩阵和外力荷载列阵。
The dynamic response of the Time Dependent System of bridge,road vehicle which would be used the moving mass and combines could be computed,based on the platform of ANSYS that was the further development of APDL language in ANSYS.The simulation could present mass matrix,stiffness matrix,damping matrix,external load array of the dynamic response of the Time Dependent System of vehicle-bridge when the different types of vehicles ran on the bridge
