Research of a Piezoelectric Driving Linear Movement Device
This paper presents a vibrator of linear standing wave ultrasonic driving. The driving vibrator works with in-plane bending vibration modes and the vibrator structure which contacts with the guide on both sides is long ring and increases driving force . Based on mode analysis, the working principle of long ring vibrator is analyzed. The vibrator of linear standing wave ultrasonic driving is developed, which has been tested and analyzed. The experimental results further verify the correctness of the theory analysis.
