Abstract


With the upgrading of car ownership, automobile traffic safety has increasingly become the focus of attention. When the car bring convenience to people, it also bring huge impact and destruction to people’s lives because of the car accident. In China, fair treatment and fairness for accidents have posed a severe test to the development of a harmonious society. Therefore, how to use the theory of computer simulation to research the problem of accident reconstruction comprehensive and rightly has become an important topic of social significance.The study of accident reconstruction possesses important practical significance. There are many research results for this field, at home and abroad. Combining with the characteristics of civil current traffic, current situation of incident process and the need of accident,this article has made the overall design of reproduction system.First, for the object of vehicle, based on reasonable assumptions, it has established the models contrary to the different types of corresponding collision using the kinetic energy theorem,angular momentum theorem and momentum theorem.Meanwhile, to study the vehicle collision theory in-depth based on a typical case of accident. It has achieved the simulation of reconstruction for vehicle collision accidents in a virtual environment combining the collision theory into computer simulation. On this basis, it has also studied the parameter optimization method of reconstruction for collision accidents in-depth from the computer iteration. For the object of vehicle stop position,it has completed the sensitivity analysis of nine parameters which impact greater weight on the results to debug and optimize the simulation accuracy of accident reconstruction. Finally, it has brought the above research and analysis to two traffic simulation cases using Pc-crash software. It has rightly reconstructed the collision accidents. The simulation results not only match reality, but also verify the analytical methods.The entire research results have helped to the reconstruction of collision accidents and provided with reference value to the judgment of traffic accidents.
