In order to establish the model of debris in automobile crash with little error for accident reconstruction, the effect degree of factors affecting thrown distance of elastic, elastic-plastic, and plastic debris is studied by simulating test, which is preformed by kinetic simulation model of debris built in Ansys/Ls-Dyna. The kinetic behavior of elastic, elastic-plastic, plastic debris in different thrown condition is obtained by simulating test. Based on the results of simulating test, the correlation degree between thrown distance and thrown height, thrown angle, thrown velocity are analyzed by grey connection. The correlation order is calculated by method of grey connection analysis. The results show that thrown velocity has strong effect on thrown distance, the second is thrown height, and the last is thrown angle.
