| 摘 要： | 应用ANSYS软件建立了平台和冰相互作用的有限元模型,构建了自升式平台的冰激振动模型,并计算基于2种冰力模型的自升式平台的动力响应。此动力分析方法具有建模方便和计算精度高的特点。以某自升式平台为例,计算了冰和平台结构相互作用的耦合效应,为自升式平台冰激振动安全评估提供了参考依据。

| Abstract: | In this paper,ANSYS software is used to formulate the finite element model of interaction between platform and ice,the ice-induced vibration model of jack-up platform is then constructed,and the dynamic responses of jack-up platform are computed based on 2 ice force models.The dynamic analysis method is characterized by convenience for modeling and high computational precision.The coupling effects of interaction between ice and platform structure are computed by taking a jack-up platform as an example,which will provide referential basis for the safety assessment of ice-induced vibration of jack-up platform. |
