| Outline of Final Research Achievements |
The realization of controllable novel acoustic actuator utilizing acoustic radiation force and acoustic streaming in near acoustic field as power source was examined.
By structure-sound-fluid coupled analysis taking nonlinearity into account in finite element method, it succeeded to grasp the generation of acoustic streaming and to estimate conveying force to act on acoustic levitation object. The nonlinear motion of a levitated object which occurs when the levitated object is transported onto a vibration board with larger amplitude was improved by a sliding mode control. An acoustic turbine and acoustic air pump without any valves which apply a similar transportation principle were made as a trial, and the operating principle was confirmed experimentally. Hereafter, the improvement of their performance is expected by using the analysis of acoustic streaming effectively.
