本文提出了一种分析漂浮式风力涡轮机运动特性和结构响应--应力和变形的方法。采用分区法求解流固耦合问题。因此，我们的C++库comana，开发耦合各种求解器，增强耦合流体求解器pan MARE和结构求解器ANSYS。首先，一个简单的弹性有限元模型被用于耦合分析。本文介绍了这种有限元模型，并给出了耦合模拟的一些结果。为了使用更详细的有限元模型而不大幅增加计算时间，可以采用超单元。这个过程被描述和应用到一个例子，在波浪中的浮动浮标，以证明其适用性在流体-结构相互作用模拟。
ABSTRACT In this paper, we present a method for the analysis of the motion behaviour and also the structural response – stresses and deformations – of a floating wind turbine. A partitioned approach is chosen to solve the fluid-structure interaction problem. Therefore, our C++ library comana, developed to couple various solvers, is enhanced to couple the fluid solver pan MARE and the structural solver ANSYS. Initially, a simple elastic finite element model is used in the coupled analysis. This finite element model is described, and some results of the coupled simulation are presented. In order to use a more detailed finite element model without drastically increasing the computation time, superelements can be employed. This procedure is described and applied to an example, a floating buoy in waves, to demonstrate its applicability in fluid-structure interaction simulations.
