| 摘 要： | 简易平台是边际油田开发的主要结构形式，由于平台结构形式简单，受到动力荷载作用响应比较大。采用动态设计可以合理优化平台结构形式，达到降低平台动力响应的效果。文中以JZ20-2NW简易平台为原型，运用ANSYS有限元分析软件对其进行冰激振动下的动态优化设计。结果表明，动态设计减振效果明显，可供设计人员参考。

| Abstract: | Minimum offshore platform is the main style of engineering structure of oil and gas exploitation in marginal offshore. For minimum offshore platform has simple structure form, it will have larger response when acting vibration force. Dynamic optimum design method can optimize the platform structure form in order to reduce the response of platform under vibration force. In this paper, author utilized the ANSYS FEM software to give a dynamic optimum design of the JZ20-2NW minimum offshore platform when acting ice-induced vibration force. The optimal design result indicated that, the dynamic optimum design can efficiently control the vibration response. This method can be referenced by designer. |
