| 摘 要： | 为研究公路桥梁在各种复杂车辆行驶工况下的车桥耦合振动响应,提出基于ANSYS单一环境下的车桥耦合振动响应数值分析方法,该方法将桥梁与车辆模型均独立建立于ANSYS环境下,其耦合作用关系通过APDL编程语言计算并将其在任意时刻施加于车辆及桥梁结构,最终得到振动的时程响应.通过参考文献验证该方法正确,并对一座大跨连续梁桥在2～8辆车以各种常见车速行驶等工况下的车桥耦合振动响应进行了分析计算,总结了挠度、弯矩冲击系数的变化规律. |

| Abstract: | For discuss the respond of coupled vibration of vehicle-bridge in complex vehicle driving conditions,a vehicle-bridge coupled vibration numerical analysis method is presented based on ANSYS.the bridge and vehicle model are established in ANSYS environment separately and the coupled vibration relationship is calculated by APDL language which can be imposed on vehicles and bridge structures at any time to get the vibration schedule response.Through comparison with references,it proved that this method can be ... |
