【摘要】 海上风机结构是一个相对复杂的结构系统,其动力响应受到多种环境因素影响,且多种荷载之间的相互作用是一种非线性行为。此外,风力机不同组成部分之间都有其独特特性,结构间的耦合作用决定着风机在非平稳环境力作用下的整体动力反应。分别综述了风机叶片的转动与弹性变形的耦合、塔架与叶片的耦合、塔架的优化设计、基础的模型以及结构随参数变化敏感性分析。最后对未来有待于进一步研究的问题进行介绍。更多还原

【Abstract】 An offshore wind turbine can be considered as a relatively complex structural system since several environmental loads affect its dynamic behavior and their mutual interaction should be considered as nonlinear phenomena.Besides different parts of the offshore wind turbine have their own peculiar features,whose mutual interaction determines the overall dynamic response under non-stationary environmental loads.The coupling between the blade,rotation and its elastic deformation as well as wind turbine tower and the blade,the optimization of a steel tower,foundation model and parameter sensitivity of dynamic behavior are discussed in this paper.Finally,some problems existed in the further research on the offshore wind turbines are presented.更多还原
