两车直角侧面碰撞事故中车速的计算方法

在直角侧面碰撞事故中,通常会采用最可靠的理论依据“动量守恒定律”获得两车碰撞时的速度,但当两车碰撞后的运动状态非常复杂时,计算得出的结果误差较大,本文采用经验公式方法和仪表卡滞方法获取两车碰撞时的速度,进一步验证利用“动量守恒定律”获得两车碰撞时速度的准确性。

In right angle side impact accidents,the"law of conservation of momentum"which is considered as the most reliable theoretical basis is usually used to obtain the colliding speed of two vehicles.However,when the after-collision motion states of two vehicles are very complex,the calculated results have a significant error.This article uses both the empirical formula method and the mstrument stuck method to obtain the colliding speed of two vehicles to further verify the accuracy of the method of using the "law of conservation of momentum"to obtain the colliding speed of the two vehicles involved in the road accident.
