Any kind of vibration present in the machines and flexible structures are undesirable because it causes unpleasant noises, unwanted stress in structures, and malfunction or failure of system. Now a day’s Piezoelectric materials are used as sensors and actuators to control the system in terms of reducing the vibrations amplitude and frequency so as to improve the efficiency of the system. In the present work a finite element model is developed for the vibration control of beams with distributed piezoelectric sensors and actuators.Smart beam considered in the analysis is modelled in simply supported configuration with piezoelectric patches bonded symmetrically on the top and bottom of the beam. The static, modal and harmonic analyses were performed using the ANSYS software to determine the displacements of a Piezo single layer subjected to Voltage, strain values, fundamental modal frequencies and amplitude of vibration for a simply supported beam made of different materials with patches at different locations. The optimum locations and number of sensor and actuator pairs is identified based on the amplitude of vibrations from harmonic analysis.
