| Application of piezoelectric shunt elements, distributed in suitable configuration on the external surfaces of vibrating plate is one of the contemporary method of reduction of its vibroactivity. The two techniques are applied: passive one and active one. The aim of simulations was to compare the minimisation effect for the two attempts. The plate was excited by point harmonic force with constant amplitude. Vibrations for the first mode were considered. |
