| 摘 要： | 应用ANSYS软件建立了自升式平台和冰相互作用的数学仿真模型,对自升式平台进行了动力分析和桩腿的极限强度和疲劳强度校核。应用本模型对渤海某自升式平台桩腿进行的强度校核和不同海冰参数下平台桩腿的冰激疲劳损伤实例分析表明,本文的研究结果为自升式平台冰激疲劳设计提供了一个有效的方法,并为自升式平台在冰区的使用提供了依据。

| Abstract: | The digital model for interactive action between ice and platform was established by applying the ANSYS software system, and the dynamic analysis of jack-up platform was performed, and the ultimate and fatigue strength of platform was assessed. The strength of a jack- up platform serviced in the Bohai Sea was checked by use of the method in this paper. The ice- induced fatigue damage of the platform leg under different ice parameters was calculated. The results in this paper provide an effective method for the ice-induced fatigue design of jack-up platforms especially in the ice zone. |
