   本文還對絆倒側翻進行了初步研究，對兩車相撞的側翻事故進行了分析，進一步建立了90與180翻車的臨界側翻速度模型和事故車輛翻滾運動模型，用于推測事故車輛的側向速度范圍、模擬側翻的運動過程，并通過實車試驗資料驗證了該模型的正確性。
2. 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(shù)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(tài)的數(shù)學模型，只有建立正確的數(shù)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(xiàn)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(tài)的計算模型及碰撞恢復系數(shù)與碰撞前、后速度的關系；其次，根據(jù)交通事故中最普遍的一維和二維碰撞的不同情況，采用恢復系數(shù)和滑動摩擦系數(shù)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(xiàn)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，并給出相應的模擬程序流程圖。
3. It's difficult to find collision movement in a sentence. 用collision movement造句挺難的
