Abstract

The generalized parametric structural schematic diagram, the generalized structural-parametric model, and the generalized matrix transfer function of an electromagnetoelastic actuator with output parameters displacements are determined by solving the wave equation with the Laplace transform, using the equation of the electromagnetolasticity in the general form, the boundary conditions on the loaded working surfaces of the actuator, and the strains along the coordinate axes. The parametric structural schematic diagram and the transfer functions of the electromagnetoelastic actuator are obtained for the calculation of the control systems for the nanomechanics. The structural-parametric model of the piezoactuator for the transverse, longitudinal, and shift piezoelectric effects are constructed. The dynamic and static characteristics of the piezoactuator with output parameter displacement are obtained.

Summary

Introduction

Let us consider the role of an electromagnetoelastic actuator on the piezoeffect, the piezomagnetic effect, and the electrostriction or the magnetostriction effect, which are used for precise alignment in nanomechanics and adaptive optics [1,2,3,4,5,6,7,8]. In References [6,14,15,28], the structural-parametric models and the schematic diagrams for the simplest piezoactuators were obtained, and these were transformed into the structural-parametric model of an electromagnetoelastic actuator with output displacements. Let us consider the general structural-parametric model and the parametric structural schematic diagram of an electromagnetoelastic actuator with output parameter displacement. 2 forthe thestrains electromagnetoelastic system of equations for the generalized structural-parametric model, and the generalized parametric actuator with output parameters and the Laplace transform for the displacements of the faces in the structural schematic diagram are determined in Figure for the electromagnetoelastic actuator with form: output parameters and the Laplace transform for the of the faces
