Abstract


With the rapid development of China's national economy , the automotive industry and road transport industry has also been a rapid development . Car ownership increased dramatically , resulting in road traffic accidents are frequent , not only threatens the safety of people's lives and property , and also a lot of inconvenience for road traffic management . In many road traffic accidents , vehicle collision accident is the most serious hazards is also the largest comprehensive car collisions , the system has become the most urgent research topic before the world . Based on reasonable classification of collision , the vehicle as a research object , based on the make reasonable to assume that the use of kinetic energy theorem , conservation of momentum, angular momentum moment theorem mechanics theory , based on the different accident collision the type of to build collision theory model , to do classified discuss speed before and after the collision and the vehicle . The article then use kinematics theory of the movement of the vehicle dynamics analysis , the Accident Reconstruction trajectory model , and reproduction in a car crash during exercise reasonable assumptions . Accident vehicle track speed calculation model based on the typical form of the traffic accidents , and VB language as a tool for the development of a vehicle collision motion simulation software . In the the VB program form interface , select the type of collision , the accident form , enter the specific values ??of the parameters , click the command button to obtain the vehicle speed and vehicle collision trajectory , effectively improve the typical traffic accidents morphology vehicle run the speed identification work efficiency , shorten the cycle of dealing with traffic accidents . The article cited an example of a two- car collision last , to verify the practicality and accuracy of VB applications .
