【摘要】:自我国加入世界贸易组织,尤其是进入二十一世纪以来,我国经济发展迅速,与此同时我国汽车工业和交通运输业也得到了快速发展,汽车也逐渐步入中国的普通家庭,真正成为国民普遍交通工具。近年来我国机动车和机动车驾驶人保持快速增长趋势,但是我国的交通事故也一直呈现快速增长趋势。我国是世界上车辆交通事故最多的国家之一,道路交通事故死亡的绝对数已高居世界第一。在我国大力建设和谐社会的背景下,利用计算机仿真技术,进行交通事故再现研究,已经成为一个具有重要社会意义的研究课题。本文基于汽车动力学原理和车辆碰撞理论,利用计算机仿真技术,建立了一个能够将事故现场信息采集,碰撞车速计算,以及辅助再现事故的交通事故鉴定辅助系统。本文研究了事故现场信息采集的相关技术,编制了事故信息采集的数据库软件,可以较准确的对交通事故中形成的现场环境、车辆、行人以及其它痕迹检验的结果,进行事故信息记录。在对车辆碰撞事故形态进行合理分析并分类之后,运用动能定理、动量定理、动量矩定理等力学理论,建立了车辆碰撞模型。依据交通事故现场痕迹进行数据采集,并以Visual Basic语言为工具开发一套车辆碰撞的车速计算软件。最后结合车与车、车与二轮车两例的实际交通事故案例,分别运用本文所构建的交通事故鉴定辅助系统和PC-Crash交通事故再现软件,对交通事故进行反向和正向模拟,最后利用路面痕迹、车体痕迹、人体痕迹等对再现结果进行了验证。验证结果表明两种方法得出的结果在合理误差范围内都能较好的再现事故过程。
[Abstract]:Since China joined the World Trade Organization (WTO), especially in the 21 century, China's economy has developed rapidly. At the same time, China's automobile industry and transportation industry have also developed rapidly, and the automobile has gradually entered the ordinary family of China. It really became a popular means of transportation for the people. In recent years, motor vehicles and motor vehicle drivers in China maintain a rapid growth trend, but China's traffic accidents have been showing a rapid growth trend. China is one of the countries with the largest number of vehicle traffic accidents in the world, and the absolute number of road traffic accidents has been ranked first in the world. Under the background of building a harmonious society in our country, using computer simulation technology to study traffic accident reappearance has become an important research topic of social significance. Based on the principle of vehicle dynamics and the theory of vehicle collision, a traffic accident identification assistant system is established in this paper, which can collect the information of the accident site, calculate the speed of the collision, and assist the reappearance of the accident by using the computer simulation technology. In this paper, the related technology of accident site information collection is studied, and the database software of accident information collection is compiled, which can more accurately check the results of scene environment, vehicles, pedestrians and other traces formed in traffic accidents. Record accident information. After reasonable analysis and classification of vehicle collision accident, the vehicle collision model is established by using kinetic energy theorem, momentum theorem and other mechanics theories. According to the traffic accident scene trace data collection, and Visual Basic language as a tool to develop a set of vehicle collision speed calculation software. Finally, combining the actual traffic accident cases of vehicle and vehicle, vehicle and two-wheeled vehicle, the traffic accident identification assistant system and PC-Crash software are used to simulate the traffic accident in reverse and forward direction, respectively. At last, the reappearance results are verified by pavement trace, carbody trace and human body trace. The results show that the two methods can reproduce the accident process well within the reasonable error range.
