杭州湾跨海大桥车桥空间耦合振动参数分析
Keywords: 桥梁工程,斜拉桥,增量动力平衡迭代,耦合振动参数,车桥系统
Abstract:
将整个车桥系统划分为车辆与桥梁两个子系统,引入车桥系统几何协调条件和力学平衡关系,采用含增量动力平衡迭代格式的Newmark-β方法编制了汽车-桥梁系统空间耦合振动分析程序,并采用弹簧质量系统匀速通过简支梁对程序的可靠性进行了验证.然后以杭州湾跨海大桥为工程实例,运用所编制程序详细研究了车辆数目、车辆间距、不同车道、车辆相向行驶、不同路面粗糙度以及不同车速时车流通过桥梁时主梁跨中的动力响应和冲击系数.研究发现主梁跨中冲击系数随着路面粗糙度变坏而明显增大,与车辆数目、车辆间距、车辆相向行驶以及车速没有必然联系.
