In order to suppress vibration, sensitivity analysis is conducted to find an appropritate structure change. For panel structures it is necessary to obtain sensitivity on bending stiffness for the modification. However, it is difficult to estimate experimentally. For this purpose we use a scanning laser doppler vibrometer in this study, and estimate response of the rotational degree of freedom by interpolating the translational responses in many points. We derive the sensitivity on bending stiffness from the rotational responses. The validity of the proposed method is confirmed by numerical simulation and experimentally by using the scanning laser doppler vibrometer.
