事故再现中对速度计算结果的调整

Optimization of the Result of Velocity Calculation in Traffic Accident Reconstruction

针对目前国内提出的事故碰撞理论模型 ,按照一定的优化准则 ,对速度计算结果进行调整 ,使其更加合理、可靠。速度调整主要从 3个方面进行 :对碰撞点位置的调整 ;对碰撞面法线方向的调整 ;对自定义参数法向弹性恢复系数k和切向滑动摩擦系数 μ的优化。实践证明 ,经过 3方面调整后 ,计算结果有了较大的改善 。

Based on the present model of traffic accident reconstruction at home, this paper optimizes the result of velocity calculation according to some optimization rule, which makes the result more rational and more reliable The paper makes the optimization as follows: the optimization of collision position, the optimization of normal line orientation, the optimizationf parameter \%k,μ\%, which are severally defined as the normal resilience coefficient and the tangent slip friction coefficient It is proved that the result is more coincident with the actual accident after the three optimizations
