1	Rotoriniai bėgančios bangos varikliai / Rotary motors actuated by traveling flexural waves Bružas, Apolinaras 14 June 2006 (has links) The technology that has emerged in commercial products requires rigorous analytical tools for effective design of such motors. A finite element analytical model was developed to examine the excitation of flexural plate wave travelling in a rotary piezoelectric ally actuated motor. The model uses annular finite elements that are applied to predict the excitation frequency and modal response of an annular stator. This model is being developed to enable the design of efficient ultrasonic motors and it incorporates the details of the stator which include the teeth, piezo-ceramic, stator geometry, etc. Mechanical Engineering Ultragarsiniai varikliai Varikliu modeliavimas Actuated motor Rotary piezoelectric Flexural Finite element Begančios bangos varikliai Ansys modeliavimas
