汽车滚翻事故的再现分析方法

Method of Accident Reconstruction and Analysis of Rollovers

汽车滚翻事故的再现分析是一个复杂的过程,需要仔细考察汽车滚翻过程的3个阶段,包括侧滑阶段、侧翻阶段和翻滚阶段。论述了各阶段再现分析常用的模型和方法,介绍了一般计算方法或再现步骤,以及二维和三维再现的目标和技术要点,使用计算机辅助事故再现。再现分析滚翻事故中汽车运动过程及其瞬时速度和空间姿态,能够为事故处理和责任认定提供科学依据,并有助于改进车身机构和车内被动安全装置的设计。

The reconstruction of rollover accident is a complex process which needs contemplation on the three stages of a rollover accident, including Pre-trip phase, Trip phase, and Post-trip phase.The article elaborates on the common models and methods for reconstruction analysis, introducing the general computing methods or reconstruction steps, the goal and key technical points of 2-D and 3-D reconstruction and using computer to assist the analysis. In the reconstruction, the process of automobile movement, instantaneous speed and stance in the air can provide scientific evidence for dealing with the accident as well as responsibility identification. It also helps to improve the structure of auto body and the design of on board passive safety equipment.
