Dynamics of parts on narrow tracks using the multibody theory

The vibratory feeder is used to feed parts in manufacturing processes. This work applied the multibody theory to describe the dynamic behavior of rectangular and cylindrical parts. The analysis studied the following cases: insolated part, part on the horizontal plane, and part on an inclined track. A new model was proposed to find the average transportation velocity to feed rectangular parts. The Coulomb friction and the Newtonian impact theories were used to describe the influence of the effects of the friction and part elasticity into the analysis. The multibody theory is complemented with the screw theory for the analysis of the cylindrical part on the horizontal plane. These results are employed in the simulation of the dynamic part. The simulation shows the importance of the friction coefficient in the dynamic of the part on the horizontal plane and on inclined plane. The results were compared with real data of other works. The results show correlation with this data.
