ABSTRACT
This paper presents numerical analyses of the impact of the size of the sensor-actuator part on sensor-actuator efficiency. For that purpose, numerical models of a steel plate clamped on all sides were created with two piezoelectric actuators attached to it. One was used to excite the plate and the second (which could be either a standard actuator or a sensor-actuator, having different shapes and sensor part size) to reduce plates vibrations. Harmonic analyses were performed with the goal function being the minimum of the displacement vector sum of n nodes, where n can have different values depending on the case study.
