Nonlinear behavior and characterization of a piezoelectric laminated microbeam system
چکیده انگلیسی

A methodology of analyzing and characterizing the responses of a piezoelectric laminated microbeam system actuated by AC and DC voltages is developed in this research. The present development is based on the piezoelectric theory, Euler–Bernoulli hypothesis, and a newly developed periodicity–ratio (P–R) approach. The electric excitation loading on the beam is considered to be generated by AC and DC interactions. The control voltage of the piezoelectric layer and the geometric nonlinearity of the beam are also taken into account. The analysis of the nonlinear motion trend of the beam system with multiple parameters is carried out with the employment of the P–R criterion. The findings of the research are significant for the design of microbeam systems and micro-structures.


► PR criterion is effective in analyzing nonlinear behavior of piezoelectric laminated microbeam.
► The model of the microbeam system is developed.
► A periodic-chaotic region diagram is generated for varying parameters and initial conditions.
► Damping coefficient and control voltage have significant influence on the microbeam’s motion.
