[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.
