【Abstract】 Data on the relation between the types of automotive collisions and injuries were applied to set up the physical and relative mathematical mTodeling of high ratio automotive crash on the right side of the express highway and develop the relevant computer software whose use replace some automotive collision tests to determine the occupants injured judgement, automotive active and passive safe performance, etc. And using of it can also give the scientific bases for the effect of the disposition and material characteristics of automotive accessories to the occupants’ safety. Taking into account the characteristics of frontal collisions on express highway, the model of our study is a two dimensions eight free\|degree model, which can simulate the dynamic respond of the front and back occupants in the automotive frontal collisions. The results of computer simulation and experimental test agree well. It makes clear that the modeling is precise and the computer simulation is successful.更多还原
