Abstract
In order to know the fluttering mode of the multi-articulated flat plate, the image processing technique was used. In that technique, wavelet transform was tried to apply to detect the moving body and focus points. In this study, Daubechies N2 wavelet was used for the detection. In this study, amplitude distributions and trajectory curves were investigated for the fluttering mode. From the result, the images by using wavelet transform show clearer distributions and curves than the composite images without detection. It was found that there were two modes in the fluttering mode of articulated flat plate. The trajectory curves of the articles and trailing edge showed the figure of eight.
