Abstract
This paper deals with numerical analyses of the usefulness of a 2-part piezoelement sensor-actuator on the reduction of plate's vibration and the sound pressure generated by said plate. For that purpose numerical models of a square steel plate were created. The plate is 400 mm x 400 mm x 2 mm and is clamped on all sides. 2 piezoactuators are attached to it. One is a standard homogeneous piezoactuator placed near the centreand is used to excite the plate. The other one can be either ahomogenous piezoactuator, or a 2-part element with the outer part used as an actuator and the inner part as a sensor. It's placed on the diagonal (near 1/4 of its length) and is used to reduce plate's vibration and sound pressure radiated by it. On one side the plate connected to a half sphere of air acting as a sound surroundings. Analyses were made for 4 chosen mode shapes. Results include the differences between vibration and sound pressurereduction obtained using standard piezoactuator and a sensor-actuator, how well the sensor part of the proposed element is acting compared to a local and global vibration readout from nodes as simulation of contactless sensors.
