This study presents experimental results on chaotic vibrations of a curved panel with a concentrated mass. The panel is excited with lateral periodic acceleration. In typical two ranges of the exciting frequency, chaotic responses are generated. These chaotic responses are examined with the Fourier spectra, the principal component analysis and the maximum Lyapunov exponents. The results of the panel are compared with the results of the panel without a concentrated mass. Furthermore, by changing the location of the concentrated mass, influences of the concentrated mass of the panel are examined on the chaotic responses. In the lower region of the exciting frequency, the chaotic responses are not so influenced by the concentrated mass. On the contrary, in the higher region of the exciting frequency, the maximum Lyapunov exponent of the chaotic responses are decreased as the concentrated mass of the panel is increased.
