摘要
以某下承式钢管混凝土拱桥为背景,采用ANSYS建立了车辆和桥梁模型,使用APDL语言编制了车-桥耦合振动分析程序,运用动力学迭代求解。研究了路面不平顺、车速、行车数量与车距4种因素对钢管混凝土拱桥吊杆应力冲击系数的影响。结果表明,路面不平顺、车速、行车数量与车距均会对桥梁吊杆冲击系数产生影响。
The models of a supported concrete-filled steel-tabular arch bridge and a vehicle are built by ANSYS.A vehicle-bridge coupling vibration system is developed using APDL to study the influence of pavement roughness,vehicle running speed,quantity of vehicle and vehicle spacing on impact factor of suspenders on bridge.Results have showed that the four factors all have certain influence on the impact coefficient of bridge.
