Abstract

Piezoelectric bimorphs as miniature missile rudder actuator components have the insufficient driving force, and difficult to satisfy the requirement of miniature missiles for steering gear drive. Aiming at this problem, finite element models of the piezoelectric bimorphs; Analyzes the static and dynamic characteristics of piezoelectric bimorphs; Explore the support way and the electrical connection in the way that affects the performance of the piezoelectric bimorphs output, with the method of superposition, increases the driving force of the dual piezoelectric bimorphs. The simulation results show that the finite element model of piezoelectric bimorphs can accurately describe the output performance of piezoelectric bimorphs and determine the electrical connection mode between cantilever support and parallel connection. Finite element model and the simulation results, and comparison of three layers of piezoelectric bimorphs stack driver can reach 2.7 times that of single piezoelectric bimorphs driver can get 2.5 N driving force, to satisfy the miniature missile claim to the actuator drives the driveability.
