摘要
渤海JZ20-2NW单腿导管架式海洋平台是世界上第一个安装磁流变阻尼智能减振系统的新型平台。文章针对渤海JZ20-2NW平台结构的形式与特点,建立海洋平台磁流变半主动控制的数值仿真模型,进行冰荷载作用下的数值分析。
JZ20- 2NW single- leg offshore platform located in Bohai bay is the first offshore platform with a Magnetorheological fluid（MR） damper system in the world. In this paper, the MR damper intelligent system controlled by semi - active algorithms of ice - induced vibration is studied. Considering the style and character of the offshore platform, the dynamic numerical model is established to simulate the response of offshore platform subjected to ice loads.
