Abstract To investigate the influence law of composite panels’ design parameters on their vibration characteristics, simulation analysis and model tests were conducted for three panel schemes of C/GFRP, rubber-core grid sandwich and buoyant-core one to obtain their natural frequencies and vibration acceleration level characteristics.The results showed that a C/GFRP panel has the same mass as that of a GFRP panel with equal thickness, C/GFRP panel has a better vibration suppression feature; grid sandwich panels’ vibration characteristics are mainly affected by core material properties, buoyant-core grid sandwich panel has the largest ratio of stiffness to mass, and a better suppressing action on vibrations within the range of 0~2kHz,while rubber-core one has a better suppressing action on vibrations within the frequency range of higher than 2kHz, so core material with higher damping and stiffness close to that of grid should be chosen; the 20mm equal thickness C/GFRP panel’s vibration level is slightly lower than that of buoyant-core one; the conclusions above mentioned can provide a basis for application type selection of composite panels.

Key words： intrinsic frequency vibration acceleration GFRP C/GFRP rubber-core grid sandwich buoyancy-core grid sandwich
