本文简述了研究颤振亚临界实验技术的意义及随机衰减法的发展概况,叙述了一个机翼模型的风洞实验和分析情况。结果表明,以随机衰减法为主,功率谱法为辅的颤振亚临界响应分析方法是成功的,可在风洞模型颤振实验中使用。
In this paper, the significance of research on subcritical flutter experimental technique and the development of random attenuation method are briefly described. The wind tunnel experiment and analysis of a wing model are described. The results show that the chatter subcritical response analysis method based on random attenuation method and supplemented by power spectrum method is successful and can be used in the flutter test of wind tunnel model.
