How do you define wind velocity and loading?
如何定义风速和载荷？
Rated Wind Velocity-The Rated Wind Velocity and Loading for antennas is calculated using industry standard TIA-329-C. The calculation for rated wind velocity determines the maximum wind velocity at which the mechanical stresses in the antenna are below the yield point of the materials by a safety factor of not less than 1.65 as specified in 5.1.2 of the standard.
Rated Wind Velocity calculated using this methodology is the wind speed at which an antenna can endure sustained exposure without failure.
Survival Wind Velocity- The calculation for Survival Wind Velocity determines the maximum wind velocity at which the mechanical stresses in the antenna components are just below the allowable yield strength of the mast, boom and dipole material.  Survival Wind Velocity calculated using this method is the wind speed at which an antenna cannot endure sustained exposure over longer periods of time without experiencing some degree of material deformation or malfunction.  Inspection after the survival wind speeds is recommended.
额定风速-天线的额定风速和负载是使用行业标准 TIA-3​​29-C 计算的。额定风速的计算确定了天线内机械应力低于材料屈服点且安全系数不小于标准5.1.2规定的1.65时的最大风速。
使用此方法计算的额定风速是天线能够承受持续暴露而不会发生故障的风速。
生存风速- 生存风速的计算确定了最大风力天线组件中的机械应力略低于桅杆、吊杆和偶极子材料的允许屈服强度的速度。使用此方法计算的生存风速是指天线无法承受较长时间持续暴露而不经历某种程度的材料变形或故障的风速。建议在生存风速后进行检查。
