转轮式风速仪底座支架尺寸的设计

On Stand Design of Turn Wheel Anemometer

转轮式风速仪是一种常用的测量风速的仪器,其底座支架的稳定性对测量仪的安全运行工作非常重要。以工程流体力学动量计算方法为依据,以底座自身产生的转矩大于风速仪受到风吹时的转矩为理论依据,通过分别计算风速测量仪、光度接收仪、立杆、三角支架所受到的风矩为途径,以太原地区8级风为例,设计了满足要求的底座。设计结果表明,该方法能够达到实际工程的要求。

Turn wheel anemometer is one of instruments in measuring wind speed. The stability of base stents is very important to the equipment safety operation. On the basis of engineering calculation method for fluid mechanics momentum, in addition, on the basis of its base stents torque is greater than anemometer wind torque, through calculating speed measuring instrument, respectively, pole luminosity re- ceived by the tripod, 8 level wind in Taiyuan district as an example, it is designed the base stents. After checking, the method is effective.
