COMPUTER SIMULATION AND EXPERIMENTAL RESEARCH OF THE VEHICLE IMPACT

Abstract

This paper investigates the vehicle rear impact and its consequences and analyzes the research developed in this field. In road traffic, especially in urban traffic, numerous rear collisions have taken place, resulting in serious injuries for passengers. The numerous studies that have been carried out lead to today’s internationally recognized demand on the car driver’s head restraint adjustment for an optimal protection of the neck spinal column (HWS) with regard to rear end collisions. Mathematical modeling of passenger movement during head impact may be a successful tool in establishing the neck injury mechanism, especially when working in parallel with experimental studies. In order to accomplish experimental studies for data acquisition and video and image samples analysis, the preparation of testing device are needed. Validation mathematical models using experimental tests, offers a vast range of their use. Thus, the simulation on the computer of the phenomena that take place during road events can be studied more comprehensively, and may allow optimize passive safety systems in order to diminish adverse effects of these phenomena.
