Abstract: Based on the principle of traveling wave ultrasonic feeding, one ultrasonic experiment feeding device was manufactured. The transport properties of conveying device were studied in conveying different material, effects of vibration frequency, vibration amplitude of particle on the surface, the material quality and the contact area on the delivery rate. Which has multidrivingfrequencies and alterable wavelengths, and the testing systems were proposed. It can provide test platforms for the theoretical and experiment studies on the ultrasonic feeding velocity and other macroscopic transportation performance.
