Design and Experimental Study of Ultrasonic Vibration Feeding Device With Double Symmetrical Structure

In view of the limitations traditional feeder driving mode in bulk material conveying, a new scheme ultrasonic vibration feeding device with double symmetrical axis structure is proposed based on existing traveling wave conveying device. The outer sides upper and lower straight beam sections vibrator contain convex tooth structures, piezoelectric ceramic sheets are pasted inner side; Based principle quarter wavelength principle, dynamically designed, influence geometric size frequency analyzed, bending selected as 18 order, prototype made. resonant difference measured experiment close to that obtained by theoretical analysis, Moreover, amplitude distribution surface basically consistent finite element analysis results, law types rate compared analyzed. test results show has certain capacity, adjustable range, high control accuracy, meets engineering application.
