Abstract

In 1989 the ERG&Passive Safety ad-hoc group finished a Draft Directive on the protection of car occupants in side-impact collisions. The document describes a 90 degree full-scale test for EC-type approval purpose. To assess injury the European Side Impact Durmny (EUROSID) is proposed.

EUROSID has been available in a production prototype-form for two years. The dummy has been evaluated for biofidelity and in full-scale side-impact tests. A measurement program at the dummy with respect to the most important mass distribution data, joint properties and component stiffness data has been carried out at TNO. These measurements served as a basis for a three-dimensional model of the EUROSID for the MADYMO 3D Crash Victim Simulation program. Results of biofidelity tests were used for validation.

The objective of the presented model is to contribute to the insight in the dynamic behaviour of and the injury suffered by an occupant in a side-impact collision. The paper describes the set-up of the dummy database and compares simulations with test results. Host of the model simulations appeared to correlate well with the dummy test results. Deviations of the dummy response from the ISO biofidelity requirement corridors were also indicated by the model. The arm/shoulder assembly of the model needs further evaluation since the complex interaction observed in reality is not completely represented correctly in the model yet. Further improvement of the model should take place as soon as performance results of the latest dummy version become available.
