摘    要:摘要:针对琼洲海峡跨海超大跨度斜拉桥方案,建立整车-整桥系统耦合振动分析的精细化数值仿真模型。采用空间杆系和板壳混合单元有限元方法,建立斜拉桥的动力分析模型,并计算其空间自振特性。利用多体系统动力学软件SIMPACK建立三维空间车辆精细化模型,充分考虑了各种非线性因素的影响。最后,采用基于多体系统动力学与有限元结合的联合仿真技术,计算列车以不同车速单线行车和双向对开通过该大跨度斜拉桥的空间耦合振动响应,检算该桥是否具有足够的横向、竖向刚度及良好的运营平稳性。计算结果表明:车辆运行安全性可以得到保障,舒适性指标为“优良”;桥梁的具有足够的刚度,振动状态良好。所得结果可供设计参考。

关 键 词:琼洲海峡跨海斜拉桥  耦合振动  联合仿真  多体系统动力学  有限元法
