Abstract

Previously created vibroactive pad encounters with a problem, i.e. vibrations are not fully descended, since amplitudes of vibroactive pad are lower. In microstructure replication process it causes insufficient flow of fluid, since it is directly dependent on the amplitude of excitation. As a solution for this problem stack type piezoactuator together with vibroactive pad of new construction are proposed. It is known, that stack type piezoactuators are able to reach higher amplitudes, than single piezoceramics can do, thus it is considered as a solution, in order to overcome previously mentioned problem. In this paper new construction of vibroactive pad is presented and numerically analyzed using Comsol Multiphysics 3.5a. software in order to determine its natural frequencies.
