Opis:: Finite element simulations of passive damped system applied to the simply-supported excited squared steel plate, is the aim of the analysis. The full mechanical, piezoelectric, electric and acoustic field coupling is analysed in Ansys Package. As the result the acoustic pressure radiated by plate is analysed. The results show possibility of application of the discussed method to reduction of the sound pressure level in realistic engineering structures.

Opis:: In this paper, the results of several tests concerning possible application of piezoelectric elements to reduce torsional vibrations of a beam are presented and discussed. The proposed method of application is a novel one. The piezoelectric elements are positioned in two pairs and glued to the beam at the chosen cross-section. These elements are activated using a harmonically varying voltage of the same amplitude and opposite in phase. Simulations are performed regarding the active reduction of the lowest natural frequencies of vibration of the fixed-free beam with the use of piezoelectric actuators. The results of these simulations are obtained by means of the finite element method (ANSYS).

Opis:: 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.

Opis:: In the paper results of simulation of active reduction of vibration of the free-fixed beam by piezoelectic actuators made of functionally graded materials are presented. The aim of simmulation was to estimate sensitivity of the process of reduction. The effect of the level of gradation of material properties and amplitude of the applied voltage on effectiveness of the reduction process was analyzed. The analysis was reduced to the case of excited vibrations of the first mode and was performed by application of the finite element package Ansys.

Opis:: The study is a next part of earlier works by the authors, and explores how does the sequence of activated actuators and the level of applied voltage affect the radiated acoustic energy. The analysis uses the finite element method for structural vibrations and combination of the finite element and the intensity hybrid method to assess the level of sound radiation. The vibrating element is a steel plate with glued on actuators, supported on one edge and excited by a harmonically variable, concentrated load with a constant amplitude value.
