摘　　要：本文对通信行业应用日益广泛的塔体美化外罩的体型系数进行了研究。采用高频动态测力天平技术,在紊流度为15%的格栅紊流场中对单管塔两种代表性美化外罩的刚体模型进行了风洞试验。通过对试验数据的处理得到了作用在模型上的平均风荷载,进而得出了模型的体型系数。本试验结果可以为类似美化外罩风荷载的计算提供参考。This paper researches on shape coefficients of decorated covers which have been increasingly widely used in the communication industry.Through the high frequency force balance（HFFB） test for two representative kinds of decorated covers used in monopoles carried in wind tunnel under the condition of 15%grid generated turbulent flow field,the mean wind loads on the models can be obtained,then the corresponding shape coefficients can be figured out.This test results provide reference for the calculation of the wind load on decorated cover of monopoles.
