Abstract :

In the astrophysics, the optical astronomy for the large telescopes and the antennas, the space radio telescope, the satellite telescopes, the adaptive optics and the nanotechnology are used the mechatronic systems with the electromechanical actuator based on electromagnetoelasticity (piezoelectric, piezomagnetic, electrostriction, magnetostriction effects). The piezoactuator is the piezomechanical device intended for actuation of the mechanisms, the systems or the management based on the piezoelectric effect, converts the electrical signals into the mechanical movement or the force. Using the solutions of the wave equation and the matrix equation of the electromagnetoelastic actuator with the Laplace transform and taking into account the features of the deformations along the coordinate axes, it is possible to construct the generalized structural-parametric model of the actuator and to describe its dynamic and static properties. Effects of geometric and physical parameters of electromagnetoelastic actuator and external load on its dynamic characteristics are determined. Structural-parametric model, decision wave equation and matrix equations of electromagnetoelastic actuator are obtained, its transfer functions are bult. Static and dynamic characteristics of piezoactuator are determined. For calculation of control systems for nanometric movements the generalized parametric structural schematic diagram Figure 1 and the transfer functions of the electromagnetoelastic actuator are obtained. The generalized structural-parametric model of the electromagnetoelastic actuator provides the determination of its transfer functions and use methods of control theory in calculation of its static and dynamic characteristics for the electromagnetoelastic actuator for astrophysics and optical astronomy. The transfer functions and the parametric structural schematic diagram of the piezoactuator for the transverse, longitudinal, shift piezoelectric effects are obtained from the structural-parametric model of the piezoactuator.
