Abstract
The automobile have already infiltrated the national defense construction, the national economy as well as human lives, which have become human’s essential and main transportation vehicle and played an important role in the human society's development and progress. This article formulate from the security functions of vehicles and divide the vehicle's safety assessment into three categories, namely, active safety, passive safety, pedestrian protection, the manufacturers of today's active and passive safety have put a lot of human and financial resources, through a broad range of technological innovations to improve the security situation in the vehicle; This article will divided vehicles type of collision into three categories, namely, frontal impact, side impact and offset collisions, From the three vehicle collision injury to study the situation with the human body (dummy) the injury site, the European and Euro-cap of the C-NCAP China will face the three vehicles from a comprehensive assessment of security and set the stars; In this paper, based on the actual situation and then, combined with traffic departments to provide certain data to choose a more common form of the collision and the damage sites more easily, that is, a vehicle collision and neck injury after a study to explore the mechanism of their injury and its protection ; then this article from the body structure of vehicle safety is discussed, the energy absorption by the body-type analysis, interpretation out the current body style compared to the energy absorption, high strength, high hardness of the body welcomed the reasons for the gradual, through the vehicle carrying the body of non-load-style-type comparison of the body to illustrate their respective advantages and disadvantages, and their respective collision course by simple power analysis, pointed out that the body-type carrying a large number of applications was the main reason; Finally, the safety of vehicles carried out a summary of the article and future prospects, I believe that as technology advances, the continuous development of new technologies.
Key words: vehicle safety vehicle rear collision mechanism protection
