概要

A laminated composite cylindrical shell made of CFRP was excited horizontally under a clamped-free condition. After the prepreg was wound onto a mandrel in the five layer cross-ply laminate, the shell was formed by the autoclave. Signals of vibration were processed with personal computer. The Simulink of MATLA was applied for the excitation to generate white noise, which was led to the controller of exciter. The optical fiber sensor was used to detect the displacement of the cylindrical shell wall. Exciting acceleration and response function of displacement were analyzed by FFT analyzer to determine the resonance frequencies. Modal analysis of vibration was carried out by STAR-system. It was shown that a optical fiber sensor had an effective in modal analysis of laminated composite cylindrical shell.
