並列タイトル等The Estimation Method on Flutter Boundary from Subcritical Random Responses due to Air Turbulences-Problems of Test Procedure and Data Analysis-
タイトル(掲載誌)航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-718
一般注記The objective of this article is to supplement the data analysis of the authors’previous papers[1,2]regarding the NAL’s method for estimation of flutter or divergence boundary from random responses due to turbulences in a flow. The model and equipment used in the experiment and the test procedure[1,2]are described in more detail. Stress is placed on the description of the preliminary data processing in which values of the parameters used in the data analysis were selected. The effects of the values on the estimation of the aeroelastics characteristics are shown changing them over a wide range. It is very important to use an appropriate combination of the width of the band-pass filter, sampled interval, number of data points, maximum lag of covariance, etc. It is shown for a higher mode analysis that a certain modification needs to be introduced into Akaike’s AIC program.
