Simulation Study of Lead Ball Contact with Piezoceramic Disc Type Actuators

Vibration energy harvesting is playing a key role in generating electricity. It also acts as a cram to replace the lithium and lead acid batteries. It is one of the methods of self and continuous supply of electric energy to low power devices. When the piezoelectric transducers are in the direct piezoelectric effect phenomenon, it leads to generate electrical voltage. When the mechanical pressure is applied by external means, the contact stress should be within the limits of fatigue strength of transducer, therefore, in this paper presented the simulation study of lead cylinder contact with piezoceramic disc type actuator in relation to demonstrate the principal of direct piezo electric effect. Maximum contact stress is observed under very low deflection of the piezoelectric disc type actuator during simulation.
