Ellipse Contact-Impact with Non-Fixed Position

Abstract:

The purpose of this paper is to study the contact-impact between ellipse and ground. The contact-impact position is non-fixed when the ellipse is rotated. Ellipse equations are built by generalized coordinates. The contact point is estimated by the elliptical geometric characteristics and equations. Do dynamics analysis by the method of continuous processing which uses spring damper mode in this point. This spring damper mode is based on the nonlinear spring damper model of Hunt-Crossley. Friction is ignored in this paper. Finally the numerical solution is given by Matlab.
