A Study On The Reconstructing Technique Of Vehicle Collision Accidents

The vehicle collision accidents are over 2/3 times as much as all traffic accidents. They cause a large amount of social influence and serious economic loss. Though the rollover accidents are not as much as vehicle collision accidents, they make much more economic loss and people damage. What the paper studies is the reconstruction technique of vehicle collision accidents and rollover accidents.Firstly on the basis of summarizing the research results, this paper deeply discusses the calculating model to analyze the instantaneous motion state in the vehicle collision, the interrelation among the every moving mechanics parameters in the every phase of the collision.Secondly, the paper use the simplified Gim tyre models establish the post collision movement model to analyze and calculate the mechanics movement of the vehicles during the traffic accidents.Thirdly, on the basis of deeply analyzing the tripped accidents, the paper establishes the rollover analytic model between the vehicle and the barrier and between two vehicles collision; establishes the critical rollover velocity model; establishes the roll model to simulate the movement after rollover collision.Based on theoretic deducing and real vehicle collision experiments, the paper has developed a vehicle collision and rollover collision analytic and simulative reconstruction model, which has the briefer computing and higher calculating precision, and its parameter input easy and result output type is more visual. The model system can be used in the traffic accidents analysis and identification.After finished the theory deducing and establishing the model, the paper makes out the program of the model system with the features such as living interface, easy operating, strong adaptability, visualized cartooning effect.
