摘要
应用ANSYS软件建立起自升式平台和冰相互作用的数学仿真模型,对自升式平台进行动力分析,并校核平台桩腿的极限强度和疲劳强度。方法对渤海某自升式平台桩腿进行了强度校核,计算了不同海冰参数下平台桩腿的冰激疲劳损伤。研究结果为自升式平台冰激疲劳设计提供了有效的方法,并为自升式平台在冰区的使用提供了依据。
The digital model for interactive action between ice and platform is established by applying ANSYS software system, and the dynamic analysis of jack--up platform is performed, and the ultimate and fatigue strength of platform is assessed. The strength of a jack-- up platform serviced in Bohai Sea is checked by using the method proposed in this paper, the ice--induced fatigue damage of the platform leg under different ice parameter is calculated. The results in this paper provide effective method for the ice- induced fatigue design of jack--up platforms, and it provides foundation for the use of jack--up platform in ice zone.
