| description | This paper presents an experimental study of the vibration attenuation achieved by the combined action of Constrained Layer Damping (CLD) and piezoelectric patches. The test structure is a cantilever beam excited at the clamped end, and the objective is to reduce the vibration of the free end. It will be shown that the most effective combination is to clad 25% of the length of the beam with CLD on just one side, and adhere a piezoelectric patch on the constraining layer rather than on the beam itself. It will also be shown that adding CLD and patches on both sides does not further improve attenuation. To guide the experimental analysis, and predict beam behaviour prior to testing, a model has been developed to include CLD cladding and piezoelectric patches. The model is based on the simplified Euler–Bernoulli beam but taking into account the stepped or segmented nature of the beams under consideration. Mode shapes are obtained for each segment and assembled imposing continuity. Experimental results show that the model can be used as a valid first approximation. |
