Our aim was to define a method for comparing the measurements of the dynamic properties of glued wall elements (composite plates), intended for constructing the supporting parts of machine tools and devices. The method enables a relatively fast and reliable comparison of the dynamic properties: more precisely of the amplitudes, the frequencies and the damping of the corresponding modes of the composite plates. In the frequency response function (FRF) measurements the input signal was a mechanical impulse, measured by an accelerometer, and the output signal was the resulting sound pressure at a distance of 1m from the specimen. The applicability of the method is an estimation of (i) the dimensions and the material of the walls, (ii) the core orientation, and (iii) the type of filling used in the optimum construction of composite plates for a given situation.
