椭球台高杆灯风荷载的实验研究

The experiment study of wind loading on the highstrut lamp of spheriodicity lampbed

通过风洞实验研究了多钝体高杆灯在不同水平风向角和竖向风向角下的力与力矩系数。实验结果表明：在一定的风向角下，法向阻力系数 C Dmax=1.030 ，法向弯曲力矩系数 C mmax=－0.940,轴向力系数 C Amax=0.504和 C Amin=－0.600 。

This paper presents the results of the windtunnel study of the aerodynamic force and moment coefficients on the highstrut lamp of multiple bluff body under various horizontal and vertical wind directions. The results show that in some cases, normaldrag coefficient C Dmax=1.030，normal bedingmoment Coefficient C mmax=｜－0.940｜, axialforce coefficient C Am ax=0.504, C Amin=－0.600 。
