In atmospheric boundary, the power spectral density of turbulent wind, simulated passively by the grid layer, is regulated difficultly with the problem of smaller integral length of turbulence. So the advantage of active control method is adapted to adjust the power spectral density and the integral length. Multiple fan wind tunnel in Miyazaki of Japan are used to debug many kinds of broadband turbulent wind and harmonic fluctuating wind. By using the high frequency force balance of better stability and precision to measure the buffeting force of thin plate section with testing the fluctuating wind synchronously, the impact parameters (integral length, turbulence intensity, attack angle etc) are analyzed.
