轮胎印迹识别及案例分析

轮胎印迹是轮胎在地面上滑动，摩擦生热，使轮胎橡胶产生塑性变形，并产生橡胶微粒，粘附于地面上形成的。事故现场的轮胎印迹分为三种：胎印、擦印和拖印。其中轮胎拖印是事故分析过程中最有价值的资料之一。它不仅反映了事故前后车辆的运动轨迹、轮胎状态、碰撞点的位置和制动措施，而且还可以根据印迹长度和形态分析车辆碰撞分离时刻的速度。

The Tire Trace Recognition and Case Analyzing

The tire trace is formed by the tire skidding in the ground,friction generating heat,making the tire tubber to have the plastic deformation,producing the rubber particle and sticking to the ground.In accident spot,the tire trace is divided into three kinds:tire trace,scratching trace and towing trace.Tire towing trace is one of the most valuable materials in accident analyzing process among the three kinds of tire trace.It not only reflects the vehicles movement path,tire condition,the position of colliding point and the braking measure in the accident back and forth,but also it may analyze the speed during the car colliding and separating time according to the trace length and shape.
