Analyzing Method for Vehicle Collision Based on Dent Superposition
-
摘要: 对于某些难以确定碰撞地点的汽车碰撞事故,无法应用传统方法进行分析.为此,根据撞痕及最终停车位置等基本勘查信息,应用撞痕重合法再现事故车碰撞时相互啮合的状态.以最终停车位置反推碰撞后事故车质心可能的滑行轨迹,再用优化理论确定事故车碰撞位置.对一起汽车碰撞事故的分析表明,与根据常规二维碰撞理论计算的结果相比,用基于撞痕重合的方法计算的车速误差小于2%.Abstract: 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.
