In this paper, the interactions of a translational vibratory feeder and the parts in the hop and the hop-sliding regimes are studied by means of an improved multi-term incremental harmonic balance method. It is an effective approach analyzing the interactions by introducing an analytical model of the motion of the feeding parts to the solution procedure. A generalized time-varying piece-wise linear dynamic model of the vibratory feeder is established to conduct a comprehensive investigation on the interactions, where the friction and the impact from the parts are included. The results indicate the dynamic response of the vibratory feeder affects the motion of the parts largely and the motion of the parts also affects the dynamic response in turn. The influences of the mass of the parts, the vibration angle, the installation angle, and the friction coefficient on the interactions of the vibratory feeder and the parts are discussed. The interactions are very important and not ignored.
