Abstract
The operating frequencies of the vibroactive pad used in order to improve the quality of replicas of complex microstructures during the mechanical hot imprint process, are numerically analyzed in this paper. It is known that piezoceramics changes its dynamical properties under the action of mechanical load. It is necessary to investigate dynamical properties of vibroactive pad, in order to improve the quality of replicas when planning more detailed research and development in this field in the future. Experimentally there is no possibility to determine the natural frequency for the construction to be excited, in order to reach the same modes of forms, thus modeling of the process was performed. The created mathematical model of vibroactive pad was implemented by FEM using COMSOL Multiphysics software.
