With the development of automobile industry and road transportation ， the traffic accidents happen every day in the world and become a serious society problem the vehicle collision accidents are over 2 / 3 times as much as all traffic accidents they cause a large amount of social infuence and serious economic loss therefore ， it is urgent to study vehicle collision accidents comprehensively and systematically ， and the research also is the academic foundation to analyze and deal with traffic accident it is difficult to authenticate car velocity after traffic accident to dig over locate witness is right way mechanics is avaid tool in this field it is important to establish math model and this is precondition to calculate vehicle velocity firstly on the basis of summarizing the research results ， this paper deeply discusses the calculating model to analyze the instantaneous motion state in the vehicle collision, the interrelation among the every moving mechanics parameters in the every phase of the collision secondly ， according to the collinear collision and two - dimension collision and the restitution coefficient ， the paper estabishesthe post collision movement models it proves that these models are correct and valid thirdly ， this paper try to research reconstruction of road traffic accident and put forward the method on it
對交通事故的科學分析應是建立在正確的數學模型與計算機模擬技術基礎上的定量分析，其基本條件就是要有能正確描述事故過程中汽車狀態的數學模型，只有建立正確的數學模型，才能較準確地推定事故車輛的碰撞速度。所以建立正確地車輛碰撞模型和運動模型正是汽車事故再現的關鍵問題。本文首先在總結前人研究的基礎上，深入地研究汽車碰撞理論，分析了車對車碰撞作用瞬間狀態的計算模型及碰撞恢復系數與碰撞前、后速度的關系；其次，根據交通事故中最普遍的一維和二維碰撞的不同情況，採用恢復系數和滑動摩擦系數等概念，分別建立了碰撞后車輛動力學模型；第三，對汽車碰撞事故再現進行了初步研究，確定了車對車碰撞事故模擬計算和反推計算方法，並給出相應的模擬程序流程圖。 -

Accident reappearance is usually used by two ways : 1, analysis method - status of post - accident is concluded by status of pre - accident. 2, simulation method - a serial of status was given before accident happened, and then result of accident was concluded by simulates accident with these statuses. the most possible assumption that closes to real result is deemed to the fact of pre - accident
事故再現採用的方法通常分為兩種，一種是由事故后的狀態反推事故前的狀態，稱為分析法；另一種是通過假設事故前的一系列狀態，然後模擬該假設條件下所對應的事故結果，將該結果與實際事故結果做比較，把與實際結果最接近的假設作為事故前真實狀態的方法，稱為模擬法。 -
