Geometry optimization of piezoceramic laser shutter

Abstract

Usually numerical modeling and simulation of multicomponent piezoelectric actuators lead to the large number of recurred calculations with different geometrical parameters of the actuator. The exchanges in the modal shape sequence are a general case problem concerning to all mechanical structures. This problem is also important for optimization, since calculations are tied both to eigenfrequencies and eigenforms. If the eigenfrequency is chosen incorrectly, the piezoactuator will not function, so it is very important to numerically determine eigenforms. In this paper are overlooked piezoelectric actuators concept and urgency, proposed model of a laser shutter and piezoelectric laser gate, analysis of geometrical parameters optimization is done. What is more, influence of geometrical parameters and advantage of the domination coefficients are presented, calculations, results and conclusions are given.
