【摘要】 论文针对重大工程建设规划过程中对微气象风力统计数据的需求，突破风向自适应的风压取样方式与复杂构件的非密闭气室压损计算的关键技术。首先，通过对风压取样方式结构进行特殊设计；其次，针对非密闭气室压损问题通过气体管道压损公式建立数学模型，提出一种新的压损补偿方法；最后，根据风压与风速关系间接计算出风速并对数据进行误差分析。实验结果表明：在0～12m/s风速下，求得补偿常数ε约为0.2514；对测风数据分析风速相对误差不超过5%。论文为大规模地区微气象统计特性的分析提供一种新型的风速测量方法。更多还原

【Abstract】 Aiming at the demand of micro meteorological wind statistics in the process of major engineering construction planning,this paper breaks through the key technologies of wind pressure sampling mode with adaptive wind direction and pressure loss calculation of non closed chamber of complex components. Firstly,through the special design of wind pressure sampling mode and structure. Secondly,aiming at the pressure loss problem of non closed gas chamber,a mathematical model is established by the pressure loss formula of gas pipeline,and a new pressure loss compensation method is proposed. Finally,according to the relationship between wind pressure and wind speed,the wind speed is calculated indirectly and the error of the data is analyzed. The experimental results show that the compensation constant ε is about 0.2514 under the wind speed of 0～12m/s. The relative error of wind speed in the analysis of wind measurement data shall not exceed 5%. This paper provides a new wind speed measurement method for the analysis of micro meteorological statistical characteristics in large-scale areas.更多还原
