| 摘 要： | 以在役WZ12-1平台为原型建立导管架平台的有限元模型,将沿导管架桩腿分布的载荷转化为等效节点力进行加载,将桩基的作用用弹簧-阻尼单元模拟,忽略导管架附连水质量的影响进行有限元分析。通过构造ETMD减振系统,设置合适的系统参数,分析了随机波浪载荷作用下有、无ETMD减振系统时导管架平台的振动情况。结果表明,ETMD减振系统能够有效控制随机波浪载荷作用下导管架平台的振动。

| Abstract: | Finite element model of jacket platform was built on WZ12-1 platform,the loads distributed along the platform leg was regarded as equivalent nodal force.The pile foundation effect was simulated with spring damping unit.And the finite element analysis was made with omitting the impact of water quality attaching on jacket.The vibration behavior of jacket platform was analyzed under the random wave loads with and without extended tuned mass damper(ETMD) system by building ETMD system and setting proper system parameters.The results indicated the ETMD system could effectively control the vibration of jacket platform under the random wave loads. |
