Research On Wind Velocity Control And Data Acquisition Processing System For 0FDY-1.2 Wind-Tunnel

Wind velocity control and data acquisition processing are indispensable sections in wind tunnel experiment. The good and bad measurement of test system capability directly influences the efficiency of wind tunnel experiment and the accuracy of experimental data.The wind velocity control and data acquisition processing system for 0FDY-1.2 low-speed wind erosion tunnel is developed in this thesis. The wind velocity control system is completed, and a suit of software which can control wind velocity and data acquisition in general-purpose calculator is designed by LabWindows/CVI. It compensate the insufficiency of original data acquisition processing system, and it can expediently collect, deposit, display and analyze real-time trial data of outside and inside. After debugging and contrastive experiment, and sheltered cultivation experimental region in WuChuan, Inner Mongolia and grassland field test of ZhaoHe, DaMao, and this system is proved to be reliable and practical, consequently supplying precondition for latter researches such as soil/wind erosion and other structure's aerial dynamic characters.
