10米风杆优化设计及有限元分析

Optimization design and finite element analysis of 10 meter wind pole

风是气象观测要素之一,根据中国气象局业务观测规范要求,需要测量10 m高度处的风速风向,因此在地面自动气象站中,10米风杆是常用的安装部件。文章在对原10米风杆现场测试失效原因分析的基础上,采用优化设计及系统设计等方法,从基础结构、杆体结构、材质选择等方面进行了改进,通过有限元分析的方法对风杆进行受力和变形量的计算分析,结果表明优化后的风杆具有更高的稳定性、可靠性及经济性。

Wind is one of the elements of meteorological observation.According to the operational observation specification of China Meteorological Administration,it is necessary to measure the wind speed and wind direction at a height of 10 m.Therefore,in the ground automatic weather station,10 meters wind pole is commonly used installation component.Based on the analysis of the failure cause of the original 10 meter wind pole in the field test,this paper adopts the methods of optimization design and system design to improve the foundation structure,pole body structure and material selection.Through the finite element analysis method,the force and deformation of the wind pole are calculated and analyzed.The results show that the optimized wind pole has higher stability,reliability and economy.
