Simulation Analysis of Traffic Accidents Reconstruction Based on Reverse-Reasoning Method

Firstly, the article researched on the theory and practice of two-vehicle central collision and two-vehicle eccentric impact (collision), proved that all kinds of complex two-dimension collision can transform into one-dimension collision with theory analysis. Secondly introduced collision parameter k and u, established vehicle speed model with momentum equation and momentum matrix equation, dispeled affection of impulsive force distributing coefficient by quadratic optimizing, and established accident reconstruction model of two-vehicle collision based on reverse-reasoning method, realized two calculate modes. Finally, the method upwards was effective and feasible by validating with actual cases. We also find that the two basic hypothesis of traffic accident had effect on accident reconstruction, it need to research and optimization in the future.
