非恒定滑动摩擦系数振动系统等效线性化计算方法研究 - 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
对交通事故的科学分析应是建立在正确的数学模型与计算机模拟技术基础上的定量分析,其基本条件就是要有能正确描述事故过程中汽车状态的数学模型,只有建立正确的数学模型,才能较准确地推定事故车辆的碰撞速度。所以建立正确地车辆碰撞模型和运动模型正是汽车事故再现的关键问题。本文首先在总结前人研究的基础上,深入地研究汽车碰撞理论,分析了车对车碰撞作用瞬间状态的计算模型及碰撞恢复系数与碰撞前、后速度的关系;其次,根据交通事故中最普遍的一维和二维碰撞的不同情况,采用恢复系数和滑动摩擦系数等概念,分别建立了碰撞后车辆动力学模型;第三,对汽车碰撞事故再现进行了初步研究,确定了车对车碰撞事故模拟计算和反推计算方法,并给出相应的模拟程序流程图。
