Abstract：To support the optimal design and application of vibratory feeders,we investigated the vibration characteristics and stability of single-mass and dual-mass inertial vibratory feeders.After establishing the dynamic models and differential equations for both types of feeders,we calculated their rigid-body dynamic responses using Laplace transforms,and simulated the coupling force between the material and the feeder via the EDEM discrete element method.Finally,we analyzed the amplitude-frequency response curves under different material loads based on actual engineering parameters.The results show that the required excitation force for the dual-mass feeder is only 20％of that for the single-mass feeder,demonstrating significant energy-saving potential.Within the material coupled mass range of 0～1 t,the amplitude variation rate of the dual-mass feeder(8.82％)is much lower than that of the single-mass feeder(32.35％),indicating superior stability.This enhanced stability originates from the dual-mass feeder's operation in the sub-resonance region,where the leftward shift of the amplitude-frequency curve caused by increased material mass counterbalances the amplitude reduction effect,thereby establishing a stable amplitude zone.These findings provide valuable insights for optimizing vibrating feeder design.
