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。
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.
