摘要

The research activities presented in this paper were carried out within Sub-Project 6 of APROSYS (Advanced PROtection SYStems), an European Project to decrease the number of fatalities on European roads. SP6 deals with the development of a pre-crash system which improves structural behavior in side crash. This paper presents different studies on actuator concepts of such a system, their performance and the integration of a favorite concept. The targeted vehicle for an actuator implementation within this study is a Daimler/Chrysler Neon (model year 1995 to 1999). For side crash structural behavior assessment, crash test results were made available as well as a numerical reference FE-model (Radioss) of the Neon, validated for Euro NCAP side impact protocol, by Cidaut, Spain, via the partnership of APROSYS. The crash tests issued that the B-pillar was massively loaded and by this, for the actuator layout, two strategies were suggested: concepts to stiffen up locally the B-pillar (E.g. door locking to rocker and to B-pillar, continuous side impact beam from A to C pillars) and concepts which redirect crash loads away from the B-pillar to other car structures non impacted (E.g. transversal structures from struck side to the tunnel or the unstruck side). A generic FE model, previously created was used to investigate the concepts.
