This paper deals with the EUROSID neck performance in terms of biofidelity in both lateral and frontal impact directions. The human reference data base comprises the results from volunteer sled tests conducted by the Naval Biodynamics Laboratory in New Orleans.
The EUROSID neck evaluation, according to these data, was performed on the basis of whole dummy sled tests -for lateral direction- and oendulum testsfor frontal direction-. In earlier APR publication (1), it was shown that EUROSID neck responses in lateral direction are rather satisfactory. This conclusion was however based on the basis of the first formulation of neck requirements as proposed by ISO/TC22/SC12/WG5 (2). Recently, these requirements have been completed (3). According to this new formulation, an evaluation of EUROSID neck performance is proposed here.
In order to illustrate the neck behaviour under frontal sollicitations a dozen frontal pendulum tests involving the EUROSID head/neck assembly were carried out by the Vehicle Research and Test Center (4). Results of one of the most severe pendulum test are presented and compared to the corridors generated at TN0 (4) using a mathematical simulation of human volunteer behaviour.
