Vibration Damping of Conventional and Smart Composite Plates using Piezoelectric Patches (Experimental)

Composite materials mixture of two or materials to meet the desired material properties. Here, in this study on attempt is made to composite plate. Structure of fiber and glass fibers. These standard plates are in comparison with the conventional material plate of same size and shape. The conventional materials plate used in this study are aluminum and mild steel. The report contains the transient vibration study of standard plates made of MS AL and synthetic fibers. The approach used for vibration is piezo electric patches. The plates are made smart by using smart materials using piezoelectric patches. As we go on supplying the voltage to a piezoelectric patch it moves to & fro and produce vibration. This is the cause of active vibrations. The produced vibrations are measured in terms of displacement, velocity and acceleration and attempt is made to reduce damp. There vibrations by attaching another piezoelectric patches at various places at opposite side of plate. One patch is excited at a time and vibrations are measured and damping is tested by exciting 6 patches at another side of plate. The result shows that as we go to the fix end cantilevers. The more damping is achieved and as we go to free end the vibrations occurred are more and less likely to damp.
