Dynamics Response of Head and Neck Under -Gx
2014
The aim of this study is to investigate the dynamics response of head and neck and helmet stability under –Gx. The test method to swing a dummy head to make an impact was established. The acceleration, force, and torque within head and neck were measured by transducers. The stability of helmet was measured by high-speed camera. As the impact acceleration peak amplitude is about 6.8G and the duration is about 42 ms, the dynamics response of head and neck is in safety limits. But the displacement of helmet is apparent. It is of important meaning to the fighter plane landing or taking off from a ship.
