中文摘要：

研制可控振动尖劈在风洞中模拟湍流边界层，寻找一种简易可行的运动控制结构和方法，试验结果证明了尖劈的低频机械振动增强了相应频率的湍流能量，增大了湍流积分长度。

英文摘要：

A controllable spire device has been developed for boundary layer simulation in wind tunnel. The feasibility and control program of the mechanism have been investigated. Experimental results have demonstrated the mechanical vibration of the spires in a certain frequency will enhance simulated turbulence energy around corresponding frequency point, and increase the integral length of turbulence.
