The aim of this study is to monitor and describe physically the natural response of the head to rapid deceleration. The methodology of using an impact simulator was adopted for simulating a load which is applied to the passengers wearing a seat belt in a head-on collision of a car at the speed of 30 km/h.
There are two major mechanical causes of various mechanisms leading to head injuries. Direct impact involving a collision of the head with another solid object at an appreciable velocity, and a non-contact impact involving a sudden head motion without direct contact with another solid object.
Ruan et al [1994] studied the impact response of the human head by a 3D finite element analysis. Willinger [1999] simulated anatomical details during deceleration.
This study aims to reveal the issue of non-contact impacts.
