Multi ultrasonic actuators with some degree of freedom
Santrauka
Usually numerical modelling and simulation of multicomponent piezoelectric actuators lead to the large number of recurred calculations with different geometrical parameters of the actuator and to the problems concerning the changes of modal shape sequences during recurred calculations. The exchanges in the modal shape sequence prevents automation of solving different problems. For this reason an improved algorithm for solving the problems related to the changes in the modal shape sequences has been proposed in the paper, also, the dependence of eigenfrequencies on various parameters of multicomponent piezoelectric actuators and problems related with the exchanges in the modal shapes sequence has been analyzed.
