摘要：Piezoelectric bimorph has many advantages such as light weight, small volume and no electromagnetic interference. It has a very significant advantage in the application of MAV and intelligent ammunition rudder control. The axial force can effectively improve the output performance and the electromechanical conversion efficiency of the bimorph. In order to provide theoretical basis for structural design and parameter optimization of axial compression bimorph, based on the assumption of Bernoulli-Euler beam, a structural dynamic model of axial compression bimorph was established based on Hamiltonian principle. Then, the static deformation, the natural vibration, the amplitude-frequency characteristic and the buckling critical load of the bimorph were deduced. Then the calculated results of the above model were compared with ANSYS simulation results and test results to verify the accuracy of the model. © 2017 IEEE.
