Abstract

A study has been made of the proposed European test procedure, using TRRL mobile deformable barrier (MDB) faces built to the EEVC specifications and a First Prototype EUROSID dummy. A series of tests using a current small car were compared to assess repeatability. The results from these tests were compared with those from tests on similar cars which had been modified to improve protection in side impacts. This series included tests on the demonstration safety car, ESV 87. Also reported are impact tests using an earlier design of MDB face constructed by Fritzmeier and using a car as "bullet" vehicle. Details of the changes incorporated in the TRRL MDB face are discussed. A computer simulation model has also been used to study the side impact injury process.

The study showed that the test procedure was effective, giving reasonable but not perfect repeatability. The importance of careful control of test parameters was demonstrated some of which have important implications for the test requirements. Both the TRRL MDB face and the EUROSID dummy performed well, clearly showing the desirability of having multiple instrumented ribs and using multiple criteria for assessing thoracic injury risk.
