中文摘要：

区别于基于风力系数的传统风载效应分析方法，提出采用RANS与Newmark格式，通过在流场与结构界面建立数据映射来实现考虑实际风载的定日镜流固耦合分析，并将其应用于一个4m×4m的定日镜上。分析表明：该定日镜结构的变形与仰角之间关系复杂，仰角为60°时，由于涡脱落等效应的影响，定日镜结构上会产生较大的变形和应力，其结果可为定目镜的优化设计与运行保护策略的建立奠定分析基础。

英文摘要：

Distinguished from conventional wind load analyses based upon static wind pressure coefficient, the formulation mixing RANS and Newmark was adopted, the data mapping of flow field and structure interface was established to realize considering the actual wind load heliostat fluid-structure interaction analysis, which was used to analyze the deformation of 4 m × 4 m heliostat bearing wind. The results show that the relationship between structure deformation of heliostat and elevation angle is complex. When the elevation angle is 60 degree, the structure of heliostat shows a local maximum response because of the turbulence. Then the confidence in optimizing the structure of heliostat and improving the protection strategy can be established.
