Purpose: In this paper we want to describe the work of Design Method's research group of Dept. of Mechanical Engineering of Salerno University, in the research sector concerning passive pedestrian safety for vehicles, taking into account models FEM used and developed for vehicle design and optimization. Design/methodology/approach: Our carried out models show a very good degree of Numeric/Experimental correlation, and also we've numerically certified our virtual impactors, designed following EEVC-WG17 requirements. These impactors have been tested at higher speed and we have had a good correlation, even if some difficulties there was, regarding the critical behaviour of the foam that covers some impactors, solved following different model-design optimization methods. Findings: Best results obtained and described in this paper are relating to impactors modelling and certification, and Experimental/Numerical correlation of crash tests. Research limitations/implications: The reaching of the elevated pedestrian safety performance, compatibly with the others, sometimes conflicting, performances, is one of the main targets to reach for the automotive industry by now and, above all, for the future. Practical implications: Statistic studies carried out during last decades have underlined as pedestrians-with a prevalence of children and elderly-are a category with great risk of die in car accidents, especially during the collision with the front part of motor vehicles, particularly in the urban areas: according to recent investigations of a research committee of the European Community (CEC 2001), the risk of death in case of accident is, for pedestrians and cyclists, equal respectively to 9 and 8 times vehicle occupants one. Originality/value: In such a context, this paper is intended to study the pedestrian injury at the impact with vehicles and methods of designing and constructing vehicles in order to reduce the damage itself.
