Analyzing Method for Vehicle Collision Based on Dent Superposition

  • The traditional method is not applicable to analyzing some vehicle collision accidents without the definite colliding positions.To solve this problem,a dent superposition method was proposed,in which the dents on involved vehicles are superposed to represent their meshing state at the colliding moment based on basic site investigation information such as dents on the vehicles and their stop positions.The trajectories of vehicle centroids are inferred from their stop positions,and the colliding position is determined by the optimization theory.The analysis result of a vehicle collision case shows that the error in calculated speed is less than 2% obtained by the proposed method compared with that obtained by the two-dimensional collision theory.
