大型商用车转弯交通事故分析
摘要
据统计，在道路交通事故中，因汽车翻车造成的事故占整个事故的42%以上。汽车翻车后不但造成经济损失，而且造成人员伤亡。因此，本文针对翻车事故，分析造成翻车事故的各种因素及作用机理，并对其采用事故树的方法进行分析，在寻找出可能导致该事故发生的原因基础上，制作出安全检查表，为事故的预防和评价提供依据。在汽车行驶中中，侧翻是其中一种最为严重并且威胁成员安全的事故。侧翻可以定义为能够使大型商用车绕其纵轴旋转90度或更多以至于车身同地面接触的任何一种操纵。侧翻可以由一个或一系列综合因素产生。它可以发生在平直的水平地面上，并且大型商用车的侧向加速度达到一定的数值，该数值要超过大型商用车侧面重量转移到车轮上所抵消的加速度值。通过有坡度的路面（或无路情况）时由于不平路面的冲击，地面松软或其他障碍物会促使侧向压力提高从而使大型商用车“失足”。
   侧翻过程是一个包括作用在大型商用车上和大型商用车里的力的相互作用的复杂过程。侧翻受操纵和高速公路的影响。人们已经通过理论分析以及包括一系列复杂设备的模型实验研究侧翻过程。这个过程很容易通过静态基本结构实验来理解（忽略惯性和滚动平面上的加速度），并且促进发展更加复杂的模型。

abstract
    According to statistics, in the road traffic accident, because the car rollover accident caused by more than 42% of the total accidents. The car overturned after not only caused economic losses and casualties. Therefore, this paper in view of the rollover accident. Analysis the various factors and mechanism of action of rollover accident causing. And the using method of fault tree analysis, looking for may lead to the occurrence of the accident reason of produce the safety check list, and to provide a basis for accident prevention and evaluation.In the car, rollover is one of the most serious threats and members of the security accident. Rollover can be defined as can make the vehicle around its longitudinal axis rotated 90 degrees or more that body contact with the ground of any a kind of manipulation. Rollover can be generated by one or a series of comprehensive factors. It can happen on the flat ground, and the lateral acceleration of the vehicle reaches a certain value, which is more than the acceleration value that is offset by the side weight of the vehicle to the wheel.Through the slope of the road (or no) due to the impact of uneven road. The ground is soft or other obstacles were prompted lateral pressure to improve so that the vehicle "slip".
    The rollover process is a complex process including the effect on the vehicle and the vehicle force interaction. Effect of rollover from manipulation and highway. It has been through theoretical analysis and Experimental Research on Rollover Model process includes a series of complex equipment. This process is easy to understand (ignore the acceleration of inertia and the rolling plane), and promote the development of more complex models.
    By theoretical analysis method in this paper, the large commercial vehicle rollover occurred when turning and drift of stress analysis. And the kinematics formula of large commercial vehicle turning is introduced. Then the author discusses the actual situation, and derives the condition of the vehicle safety turning. When the large commercial vehicle wheelbase must, large commercial vehicles and road surface friction coefficient is large, large commercial vehicle safety rate more.
Keywords: large commercial vehicle rollover accidents; safety analysis;
