Abstract
This sheet deals with characteristics of the oblique impact system, which is composed of the ball and flat surface. The impact system is modeled by both a nonlinear spring and a nonlinear dashpot using Hertz's contact theory. This model is applied to the oblique impact system of ball. The characteristics of the oblique impact were obtained by using this model. The results show that the stiffness of impact system was not affect ed the spin rate and the ratio of angle. Also, in the case of increase the coefficient of restitution, the spin rate was increased and the angel of reflection was decreased.
