DESIGN OF A RESONANT-TYPE INERTIA DRIVE LINEAR MOTOR BASED ON PIEZOELECTRIC ASYMMETRIC TUNING-FORK ACTUATOR
With harmonic resonant vibration synthesis, resonant-type piezoelectric impact motors show a great improvement of power output capability against traditional piezoelectric impact motors.In this paper, a resonant-type inertia drive linear motor with piezoelectric asymmetric tuning-fork actuator is proposed.Structural design and working principle of the motor is descripted.A simplified mechanical model of the piezoelectric asymmetric tuning-fork actuator is established to investigate the frequency trends of the anti-phase and in-phase bending vibration modes of the structure.With FEA simulation, modal analysis of the structure is used to determine the optimal sizes of the components, resulting 1∶2 frequency ratio of the two bending vibration modes.A prototype motor is manufactured to test the characteristics of the two vibration modes and their frequency trends.
