EIGHT-DEGREES-OF-FREEDOM KINEMATIC MODEL DEMONSTRATING AFTER-IMPACT MOTORCYCLE'S BEHAVIOR

摘要

Deriving a precise kinematic model to describe a motorcycle's behavior after impact is a prerequisite for developing a fact-analytical tool for motorcycle accidents. Therefore, this paper successfully derives a high-degrees-of-freedom model. Twenty-four time-response illustrations of simulation results demonstrate the dynamic behavior of the proposed model. A surface diagram is revealed while investigating the vehicle tracking. The twenty-four illustrations include motion, velocity and acceleration with respect to longitudinal, lateral, vertical, pitching, yawing, vehicle rolling, rider rolling, and steering variations. The model proposed herein can be effectively used to preliminarily analyze the tendency toward stability or toward rolling of a motorcycle after a collision.
