摘要
探讨了亚音速二维壁板颤振模型的设计方法和模型风洞试验技术。在模型风洞试验时,采用单点激光测振仪提取壁板中点的气动弹性响应信号,观察到了壁板模型的颤振现象。模型风洞试验得到的二维壁板颤振临界速度与理论分析结果具有良好的一致性。
The design method of subsonic panel flutter model and the model wind tunnel test technolo- gy are discussed in the paper. The laser vibration measure system is used to pick up the response sig- nals of the middle point of the 2D panel. The flutter phenomenon of the panel is observed. The flutter speed measured in the wind tunnel test agrees with one resulted from the theoretical analysis.
