| 摘 要： | 从提高计算机模拟汽车碰撞事故的实用性出发,以物理学和力学为基础,结合恢复系数、摩擦系数等建立车辆碰撞的力学模型,以已知的碰撞参数离差最小为目标,提出采用穷举法,通过计算机编程来实现基于最小二乘法模型的目标函数求解,进行汽车碰撞事故再现分析,通过对一实际交通事故案例的分析,验证了所采用的方法对事故再现的实用性。

| Abstract: | Based on physics and mechanics,a vehicle collision model is set up using re '.itution coefficient and friction coefficient.With an objective of minimizing the collision parameters' deviation, a new method is proposed that is programmed with Visual Basic 6.0 and based on the exhaustion method to find the objective function. Applying it to the analysis of an real collision case proves the effectiveness of the method. |
