Rapid Algorithm of High Risky Position on Car Hood for Pedestrian Crash based- Computer Simulation

Introduction This paper has proved that the HIC of local Car hood crash area is relative to the distance between the crash point and potential secondary crash point, and with the rigidity of the second crash point, in the process of protection for pedestrians. The pertinence formula was built and the high risky spot of each local crash areas was doped out quickly, and the accuracy of the formula is validated by the subsequent real car crash test. When the vehicles and the pedestrian have the crash accident, the pedestrian casualty rate is very high, develops the pedestrian to protect the research positively, particularly the forehead crash trouble-free service, regarding the guardian vehicle crash's in weak one "the pedestrian", has the very vital significance.
