Abstract

The focus of this study is on flexible actuators which act as soft muscles and can produce large amount of deflection (bending) on the application low voltage less than 4V, which can be applied for various applications of robotic arms, manipulators, medical devices, aerospace applications and for structural health monitoring. In this study, vibration analysis of beam structure of polymer composite of (PVDF/CNF) material is carried out using Finite element analysis. The vibration analysis is carried out for six modes withone end fixed and both end fixed boundary conditions. The obtained results from the analysis showed the minimum failure frequency with different mode shapes at different boundary conditions. The analysis can be very much helpful in prediction of the safe working conditions for the complex structures.
