摘要
完成了风洞数据采集与处理系统方案设计及风速闭环控制方案设计,在此基础上实现系统的硬件及软件设计。系统软件采用美国NI公司的LabVIEW6.1为平台进行开发。并完成了落差系数、动压时间稳定姓、轴向静压梯度、边界层及湍流度等的流场校测。系统具有很好的使用效果。
A general scheme of the data acquisition and processing system for a wind tunnel was firstly put forward,then a closed-loop control system for the wind tunnel was designed,and finally the hardware and software of the systems were accomplished actually.The software of the system was developed on the LabVIEW6.1 platform of American NI Company.Using the designed systems,the dynamic pressure drop coefficient,dynamic pressure time stability,axial static pressure gradient,calibration of boundary layer and degree of turbulence were measured.The designed systems possess satisfied effects.
