Abstract

The objective of this paper is to show the potential of the multi-body vehicle models for crashworthiness optimization of a fleet. To this end a fleet study on offset frontal impacts was performed in which sensitivities of relevant accident and design parameters were investigated by means of parameter sweeps over these parameters. The accident parameters included vehicle type, safety belt usage and occupant size. The design parameters relate to the front-end geometry of the two smaller vehicles and the front-end stiffness of all vehicles. A total set of 2500 scenarios was simulated. Analysis of results was done on the basis of measures for the overall injury risk and on the basis of separate injury values for different body regions. For the separate injury values clear trends are observed with respect to variations in design variables. For overall injury risk measures these trends are not so clear due to contradicting influences of the design variables on separate injuries. This complicates usage of the overall injury measures. For the covering abstract see ITRD E825082.
