【摘要】:为实现汽车与摩托车碰撞事故的仿真再现分析,基于经典动力学理论,构建事故碰撞动力学模型及摩托车翻滚运动轨迹模型,初步探讨碰撞事故的人车分离问题。针对事故案例,分别利用PC-Crash软件与构建的碰撞动力学模型及轨迹模型进行再现分析,对比轨迹再现结果和现场残留痕迹。结果表明:汽车的二维速度、角速度及摩托车的三维翻滚角速度与PC-Crash软件分析结果相接近;汽车与摩托车运动轨迹的再现与事故现场痕迹相符合。
[Abstract]:In order to realize the simulation and reappearance analysis of automobile-motorcycle collision accident, based on the classical dynamics theory, the collision dynamics model and the motorcycle roll-over trajectory model are constructed, and the problem of separation between human and vehicle in the collision accident is discussed preliminarily. According to the accident case, the collision dynamics model and trajectory model are analyzed by using PC-Crash software, and the results of trajectory reconstruction are compared with the residual trace on the spot. The results show that the two-dimensional velocity, the angular velocity and the three-dimensional rolling velocity of the motorcycle are close to those of the PC-Crash software, and the reappearance of the track of the motor vehicle and motorcycle is in agreement with the trace of the accident site.
