Study on Accident Reconstruction Model Based on Reverse-Reasoning Method

The article researches on the theory and practice of two-vehicle central collisions and two-vehicle eccentric impacts (collisions), proved that all kinds of complex two-dimensional collisions can transform into one-dimension collisions with theory analysis. Secondly, the article introduces collision parameters k and μ , established a vehicle speed model with a momentum equation and a momentum matrix equation, eliminated affection of impulsive force distributing coefficients by quadratic optimizing, and established accident reconstruction model of two-vehicle collision based on reverse-reasoning method, realized two calculate modes. Finally, the method was found to be effective and feasible by validating with actual cases. We also find that the two basic hypothesis of traffic accidents had effects on accident reconstruction, which need to be researched and optimized in the future.
