摘　　要：塔式光热电站中,定日镜结构具备要求的抗风能力是其安全运行的必要条件。文章根据风洞测压试验结果,采用多阶模态力法计算定日镜的等效静力风荷载,结果与时程分析方法相近,计算简便,具有较高的可靠度。In tower-type solar-thermal power stations,the required wind resistance of the heliostat structure is necessary for its safe operation.Based on the wind tunnel pressure test results,the article uses the multi-order modal force method to calculate the equivalent static wind load of the heliostat.The result is similar to those of the time-history analysis method,and the calculation is simple and reliable.

关 键 词：定日镜结构 风洞试验 风振
