Effect of Polarization and Gravity on Deflection of PZT-5H based Cantilever Actuator

Ritesh Kumar and Naresh Kumar Vemula


This paper examines the impact of polarization and gravity on piezoelectric actuators operating in various modes (d13 and d33). These modes are responsible for two different types of actuations like compressive and tensile. The Finite element analysis (FEA) of unimorph actuator is presented using 3D 20 node coupled element. The two different axial polarization effects are analyzed considering the effect of gravity. The displacement and stress field are studied for PZT-5H (Lead Zirconate Titanate) material. The variation of displacement and stress is presented with respect to thickness of piezoelectric actuator. In addition, the displacement field analysis of bimorph under voltaic gravity loading environment is presented.
