| Abstract: | The physical laws of the non-completely elastic collision of a pellet and a fixed-spindle pole are discussed and its gener- al formulas are derived. The influences of the collision position and the restitution coefficient on the motion of the pellet and the pole are analyzed, respectively. The loss ratio of kinetic energy is presented and the influences of the collision position and the restitution coefficient on the loss vatio are discussed. |

| Keywords: | non-completely elastic collision restitution coefficient homogeneous fixed-spindle pole |
