Wind-tunnel Test for Shape Coefficient of Monopoles with Circular Ring Platform

平台式通信单管塔高度一般30m^50m,平台、通信天线及设备所承担风荷载的精确测算对于通信单管塔设计的精细化具有重要意义。对5种平台式单管塔的刚体模型进行风洞试验,得到了作用在模型上的风荷载,并推导得到了体型系数的调整系数。成果已纳入行标,其应用可显著改善平台式通信塔经济性,同时也可提升存量塔的天线挂载能力,现已广泛应用于4G和5G网络建设。

The height of the monopoles with circular ring platform is generally 30~50 meters The accurate calculation of the wind load borne by the platform communication antennas and equipment is of great significance for the design of the monopoles.Wind tunnel tests were carried out on the rigid body models of the 5 platform monopoles and the wind load acting on the model was obtained and the adjustment coefficient of the body shape coefficient was derived.The results have been incorporated into the industry standard and its application can significantly improve the economics of the platform monopoles and can also increase the antenna mounting capacity of the stock monopoles.The results have been widely used in the 4G and 5G network construction.
