摘要

由于风力涡轮机的简化,采用解耦有限元法很难准确模拟转子系统与支撑结构之间的相互作用。因此,在使用该方法对海上风电机组(OWT)进行安全评估和动态响应研究时,模拟结果与实际响应存在偏差。本研究在理论推导的基础上提出了一种改进的解耦有限元分析方法。建立了具有等效下部结构的 10 兆瓦夹套式风电机组的简化有限元模型,并研究了风浪作用下风电机组的动态响应。通过比较全耦合分析方法和传统有限元方法的结果,讨论了传统有限元分析方法是否适用于典型风浪条件下的 OWT 动态分析。揭示了使用传统有限元方法研究或评估 OWT 复杂动态系统的局限性,并定性和定量验证了本研究提出的改进方法的有效性和适用性。随后,基于所提出的改进型解耦有限元分析方法,进行了与完全耦合试验相对应的数值计算。与传统有限元方法得出的数值结果相比,本研究提出的改进解耦有限元方法得到的结果与全耦合试验的结果更加一致。

An Improved Decoupled Finite Element Analysis Method of Ultra-Large Offshore Wind Turbine Subjected to Combined Wind-wave Actions
Owing to the simplification of the wind turbine, it is difficult to accurately simulate the interaction between the rotor system and the supporting structure using decoupling finite element method. Therefore, when using this method for safety assessment and dynamic response research of the offshore wind turbine (OWT), there is a deviation between the simulation result and the real response of the OWT. In this study, an improved decoupled finite element analysis method is proposed based on a theoretical derivation. A simplified finite element model of a 10 MW jacket OWT with an equivalent substructure was established, and the dynamic response of the OWT under wind and waves was studied. By comparing the results of the fully coupled analysis method and the traditional finite element method, the applicability of the traditional finite element analysis method to the dynamic analysis of an OWT under typical winds and waves is discussed. The limitations of using the traditional finite element method to study or evaluate an OWT complex dynamic system were revealed, and the effectiveness and applicability of the improved method proposed in this study were qualitatively and quantitatively verified. Subsequently, based on the proposed improved decoupled finite element analysis method, a numerical calculation corresponding to a fully coupled test was performed. Compared with the numerical results obtained by the traditional finite element method, the improved decoupled finite element method proposed in this study obtained more consistent results with the fully coupled test.
