- Secondly, the paper use the simplified gim tyre models establish the post collision movement model to analyze and calculate the mechanics movement of the vehicles during the traffic accidents . thirdly, on the basis of deeply analyzing the tripped accidents, the paper establishes the rollover analytic model between the vehicle and the barrier and between two vehicles collision; establishes the critical rollover velocity model; establishes the roll model to simulate the movement after rollover collision
本文還對絆倒側(cè)翻進(jìn)行了初步研究，對兩車相撞的側(cè)翻事故進(jìn)行了分析，進(jìn)一步建立了90與180翻車的臨界側(cè)翻速度模型和事故車輛翻滾運(yùn)動模型，用于推測事故車輛的側(cè)向速度范圍、模擬側(cè)翻的運(yùn)動過程，并通過實(shí)車試驗(yàn)資料驗(yàn)證了該模型的正確性。 - 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(xué)分析應(yīng)是建立在正確的數(shù)學(xué)模型與計算機(jī)模擬技術(shù)基礎(chǔ)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(xué)模型，只有建立正確的數(shù)學(xué)模型，才能較準(zhǔn)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(yùn)動模型正是汽車事故再現(xiàn)的關(guān)鍵問題。本文首先在總結(jié)前人研究的基礎(chǔ)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(fù)系數(shù)與碰撞前、后速度的關(guān)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(fù)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(xué)模型；第三，對汽車碰撞事故再現(xiàn)進(jìn)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(yīng)的模擬程序流程圖。
