【Abstract】 Solid throwing objects and their spreading field on traffic accident scene hint important details about the status of traffic accident.This paper analyzes the models involved in the correlation between crash velocity and throwing distance based on motion law of throwing objects (i.e.glass splinter).The generalized throwing motion law that is composed of parabolic motion,spring motion and rolling sliding motion is revealed. The generalized throwing motion formula is derived and the model parameters are calibrated based on the throwing motion of headlamp glass splinter. 1 tab, 2 figs,13 refs.更多还原
