Abstract	In order to study the effect of thrown condition on the rebound characteristics of elastic-plastic debris, and improved the dynamic behavior model of debris further in automobile crash. The dynamic rule of elastic-plastic's rebound parameters vary with thrown condition obtained from the kinetic simulation analysis by Ansys/Ls-Dyna. The rebound parameters indexes are vertical rebound coefficient, horizontal rebound coefficient, angle lost coefficient. The effect of rebound character on dynamic behavior after collision is discovered. Based on the meaning of rebound parameters, the nonlinear trend curve of different material nature varying with rebound parameters is given by combing qualitative analysis with quantitative calculation. The abnormal phenomena of debris's motion just like breaking rebound, is expounded. The results of simulation tests show that horizontal rebound coefficient is the key factors affecting rebound parameters when thrown height and thrown angle are certain. While the change of vertical rebound coefficient is the key factors affecting rebound parameters and angle lost coefficient affected by thrown angle.
