摘　　要：本文以一种新型双模块半潜式海工平台为研究对象,建立了相应的水动力计算模型和三维有限元分析模型,基于COMPASS THAFTS软件对该平台的运动和连接器载荷响应进行了数值模拟,并与水池模型试验结果进行了对比分析。结果表明:COMPASS THAFTS软件的数值模拟结果与试验结果吻合良好,共同反映了该平台具有良好的耐波性能;同时可以发现,平台连接器垂向载荷最大,轴向次之,横向最小,其中生存海况下垂向载荷最大值接近200 t,轴向和横向两个方向的载荷一般在几十吨的量级。文中给出的运动和连接器载荷响应规律和量值可以为该新型平台及其连接系统的优化设计和建造提供重要的参考依据。With the hydrodynamic model and three-dimensional finite element model of a new type of twomodule marine platform built as the research object, the motions and connector loads of the platform were predicted based on the COMPASS THAFTS software, the results of which were in agreement with the model tests and showed that the new type platform has a good sea-keeping performance. Furthermore, the short-term forecast results indicate that the connector loads in the vertical direction is larger than those in the other two directions, approaching 200 t while the connector loads in the axial and transverse directions are usually in the order of magnitude of dozens of tons. The prediction results obtained in this paper can serve as an important reference for the optimal design and construction of new platforms and connector systems.
