摘　　要：风敏感空间结构轻质、高柔、低阻尼,其风致耦合问题突出。对近年来该类结构的风致耦合作用研究进行分析与评述。简要阐明了流固耦合研究方法,这是风致耦合作用分析的基础。阐述了风敏感空间结构风致耦合的研究现状、有关分析方法及各自特点,主要包括风致耦合作用的简化模型方法及其附加质量和气动阻尼的获取,风洞试验与现场实测方法等,基于CFD技术的风致耦合数值模拟方法及其结构域、流体域和网格域的力学建模、数值离散方法和数值求解策略,湍流模型及特点,网格生成与网格更新、耦合界面信息传递与交换等。Wind-induced interaction of wind-sensitive spatial structures is prominent due to their lightweight, higher flexibility and lower damping. Investigation on wind-induced interaction of spatial structures in last decades was clarified and analyzed, including the simplified method, wind tunnel test and field measurement method. Furthermore, numerical simulation based on CFD technique was heavily mentioned, including how to deal with mechanical modeling of structural system, fluid field and grid system, numerical discretization technique and solution strategy, turbulence models and their characteristics, grid generation and updating as well as information transfer and exchange on interface of flow and structures and so on.
