The work consists of the introduction, two chapters, basic results of the work, conslusions and the list of used literature. Theorical methods of research are applyde in the work. The optimisation of systems of created ultrasonic motorsis carried out using programmable equipment ANSYS 6.1. This work provides analysis of own resonant freaquencies of ultrasonic actuators and establishes the dependence of amplitudes on suspense in piezoelements. The dynamic analysis of ultrasonic actuators was carred out and the trajectory of movementof exit chain points was established.
