Summary

High-speed films recorded from head on collision tests with cadavers have been analysed with respect to the angular acceleration and angular velocity which were evaluated with Smoothed Cubic-Spline Functions. These results compared with the autopsy findings in these cases and data from studies on angular acceleration to the head of squirrel monkeys carried out by Unterharnscheidt and Higgins indicate the bridging vein disruption due to rotational movement of the head is obtained when the angular acceleration exceeds 4500 rad/sec2 and/or the change in angular velocity exceeds 50 rad/sec. These tolerance levels are compared with data from collision experiments on living human beings.

Key words

Bridging veins, strain tolerance Bridging vein disruption 

Zusammenfassung

Mit Hilfe der Smoothed Cubic-Spline Functions wurden Winkelbeschleunigung und Winkelgeschwindigkeit des Kopfes auf Grund von High-speed-Filmen berechnet, die bei frontalen Kollisionen mit Leichen aufgenommen wurden. Die Resultate wurden mit den Sektionsbefunden in diesen Fällen und Daten verglichen, die bei Studien über die Winkelbeschleunigung des Kopfes von Affen (Samiri sciureus) durch Unterharnscheidt u. Higgins gewonnen wurden. Es zeigt sich, daß Rupturen der parasagittalen Brückenvenen dann auftreten, wenn die Winkelbeschleunigung des Kopfes 4500 rad/sec2 überschreitet und/oder eine Veränderung der Winkelgeschwindigkeit von mehr als 50 rad/sec vorliegt. Diese Toleranzgrößen werden mit Daten verglichen, die bei Versuchen mit lebenden Menschen gewonnen worden sind.
