| Abstract: | The selection of vibration mode is very important during the design of ultrasonic motors.It is also a significant factor infecting motor's performance.The selective principle of ultrasonic motor's vibration mode and the form of resonance mode are introduced in this paper.Using finite element analysis (FEA),motor's vibration mode and resonance frequency have been measured.Resonance frequency under different mode has been surveyed by using impedance characteristic analysis instrument.The result is in accord with FEA outcome.Finally,motor's output characteristic under different mode has been analyzed. |
