Abstract

This paper gives a further approach to provide information on the human pelvis tolerance against lateral impacts with unembalmed cadavers. The aim of this work was to verify the influence of impactor parameters as velocity and weight on the criteria measured on pelvis as force, acceleration and deflection. A previous study, presented in 1994 at the ESV Conference, concerned the establishment of behaviour laws for the pelvis response by a 23.4 kg impactor. The analysis of crash tests showed that the impacting masses are lower and the impact velocities are higher. It was essential to know the pelvis behaviour in new impact conditions. A series of 11 new tests were conducted with a guided horizontal impactor at several speeds. The impactor was flat and rigid. Its weight was 12 kg or 16 kg. From the 31 tests it is possible to propose a deflection limit value of 46 mm at 1 50% AIS greater than or equal to 2 probability. The authors propose 2 'force/deflection' corridors for impacts energies of 800 and 1100 joules. From these study results they propose: A EUROSID-1 pelvis performance criteria of 3.93 kN with a 50% AIS greater than or equal to 2 probability; A EUROSID-1 pelvis performance criteria of 6.16 kN for a 50% AIS greater than or equal to 3 probability.
