In this paper, we describe a method to investigate the fluid-structure interaction of a floating wind turbine and to analyze the global deformations and the corresponding stresses with a detailed finite element model. To solve the fluid-structure interaction problem, a partitioned approach is chosen. The in-house C++ library comana, which was developed to solve multi-physic problems by coupling existing solvers, is extended to couple the fluid solver panMARE and the structural solver ANSYS. The significance of the interaction of structural deformations and the fluid loads is pointed out for the rotor of the wind turbine. In order to enable the use of a detailed finite element model in the fluid-structure interaction simulation, a model reduction method is applied in ANSYS. As a result, an efficient stress analysis can be performed under consideration of the fluid-structure interaction.

在本文中，我们描述了一种方法，用于研究浮动风力涡轮机的流固耦合，并使用详细的有限元模型来分析整体变形和相应的应力。为了解决流固耦合问题，选择了分区方法。内部C ++库comana的开发旨在通过耦合现有求解器来解决多物理场问题，现已扩展为耦合流体求解器锅MARE和结构求解器ANSYS。对于风力涡轮机的转子，指出了结构变形和流体载荷相互作用的重要性。为了能够在流固耦合模拟中使用详细的有限元模型，在ANSYS中采用了模型简化方法。结果，可以在考虑流体-结构相互作用的情况下进行有效的应力分析。
