| 摘 要： | 通过考虑冰抗压强度与应力速率的函数关系,对Matlock模型作了适当修改,使之能够较全面地反映平台结构的冰激振动特性,同时适用于刚性结构和柔性结构动力分析。利用ANSYS软件建立了平台结构的有限元模型,并选用不同的海冰参数对渤海某导管架平台结构的动力响应和冰力进行了计算与分析,计算过程充分体现了冰与结构物相互作用的耦合,计算结果符合该平台实际冰激振动情况。

| Abstract: | Matlock model has been modified properly according to the function of sea ice strength and stress rate, in order to reflect the characteristics of ice induced vibration and to be applicable to the dynamic analyses of both rigid and flexible structures. The finite element model of platform structure is established by using ANSYS software, while different parameters of sea ice are chosen to calculate and analyze the dynamic response and ice force for a jacket platform structure in Bohai Sea. The calculation process embodies fully the interaction of ice and structure, and calculation result coincides with the actual ice induced vibration of the platform. |
