Abstract

This paper describes belted dummy injury and roof deformation in rollovers, based on analyzation of field accident investigations results. In the rate of rollover events to the amount of passenger car traffic accidents, occupants’ physical injury, and roof crash are studied from analyzing the database originally investigated by the Ministry of Transport in Japan. The ramp roll-over tests based on SAE 1857, are carried out in the laboratory. Comparison of dummy neck loadings and injury criterion (HIC) to the roof crash are presented for production vehicles. By utilizing a three-dimensional Finite Element code (PAM-CRASH), rollover simulations are conducted to observe the behavior of the roof crash in detail. Portions of this paper have been revised to incorporate new findings, results of reviews and examinations after the presentation in Paris, France.
