Research And Design Of Auxiliary Systems Accident Identified

Since China’s accession to the World Trade Organization, especially into the 21 st century, Chinese economy has developed rapidly, while Chinese automobile industry and transportation industries have been developing rapidly. Cars are gradually entering ordinary Chinese families, and truly become a national general transport. In recent years, not only our motor vehicles and motor vehicle drivers to maintain a rapid growth trend, but also our traffic accidents have been showing rapid growth trend. China is one of the largest vehicle traffic accidents all over the world, and the absolute number of road traffic fatalities has been highest in the world. In our efforts to build a harmonious society in the background, using computer simulation technology for accident reconstruction research has become a very important research topic of social significance.Auxiliary identification system for traffic accident by using computer simulation technology is established in this paper, based on the vehicle dynamics principle and vehicle collision theory. The scene of the accident information acquisition, the collision speed calculation, and the assisted reproduction accident can be realized in this system. The accident site information acquisition technology was studied and the accident information collection database software was developed, which can accurately record accident information of traffic accident scene, vehicles, pedestrians, and other signs of incident information. After a vehicle collision accident analysis and classification, according to the theorem of kinetic energy, momentum, moment of momentum theorem and so on, vehicle impact model was established. According to the data acquisition of traffic accident scene traces, and the Visual Basic language for the tool to develop a set of vehicle collision speed calculation software.Finally, the traffic accident appraisal assistant system and PC-Crash traffic accident reconstruction software were respectively used for two actual traffic accident cases of vehicle-vehicle, car to two-wheelers, and simulated the traffic accident reverse and forward. The reproduction results was verified according to the road signs, car signs, and human traces The Verified results of the two methods can better reproduce the accident within a reasonable margin of error.
