HEAD IMPACTS IN SIDE COLLISIONS: CRITERIA AND TEST METHODS

HUVUDINSLAG VID SIDOKOLLISIONER: KRITERIER OCH PROVMETODER

The purpose of this report is to study some types of possible head impact surfaces in side collision and to consider different injuries, tolerance levels and criteria. Work also included evaluation of new method of testing interior fittings in automotive environment suggested by the NHTSA (National Highway Traffic Safety Administration). The original method comprised a FMH (Free Motion Headform) head and a propulsion unit. FMH is a modified HIII head with the nose removed and the back of the head replaced by a steel plate. The head is meant to fly freely before impact at a speed of 15 mph (6.7 m/s). Since only the FMH head was accessible, free fall was used to accomplish the free flying motion. Two alternative methods were built with the FMH-head assembled on a HybridIII neck. The purpose was to get an idea of rotational acceleration in a typical side impact situation. The rotational acceleration is between 2000 and 4000 rad/s2. It was also interesting to study the effect on rotational acceleration if head impact occurred or not. The results showed that rotational acceleration was slightly lower when head impact occurred. (A)
