Abstract :

Piezoactuator nanodisplacement is used in the majority of nanomanipulators for nanotechnology, nanobiology, power engineering, microelectronics, astronomy for large compound telescopes, antennas satellite telescopes and adaptive optics equipmen and for scanning tunneling microscopes (STMs), scanning force microscopes (SFMs), and atomic force microscopes (AFMs). Piezoactuator - piezomechanical device (piezoplate) intended for actuation of mechanisms, systems or management based on the piezoelectric effect, converts electrical signals into mechanical movement or force. The investigations of static and dynamic characteristics of a piezoactuator of nano- and micrometric movements as the control object are necessary for calculation of piezodrive mechatronics systems. By solving the wave equation using the Laplace transform with allowance for the corresponding equations of the piezoeffect, the boundary conditions on loaded working surfaces of the piezoactuator, the strains along the coordinate axes, it is possible to construct the structural parametric model of the piezoactuator. The transfer functions and the parametric structure scheme for the piezoactuator of the longitudinal, transverse, shift piezoeffects are obtained from the set of equations describing the corresponding structural-parametric model of the piezoactuator. Structuralparametric model, decision wave equation and transfer functions of the piezoactuator are obtained using kinematics of deformable bodies. Effects of geometric and physical parameters of the piezoactuator and external load on its dynamic characteristics are determined. For calculation of mechatronics systems for nanometric movements with the piezoactuator the parametric structural schematic diagrams and the transfer functions of the piezoactuator are obtained. Static and dynamic characteristics of the piezoactuator are determined. The generalized structural-parametric model of the piezoactuator provides the determination of its transfer functions and use automatic control theory for finding static and dynamic characteristics of the piezoactuator nanodisplacement.
