Abstract

Abstract: The biomechanical response of human head and neck was studied to safeguard the helicopter aircrew in the traction escape process. A finite element model of human head and neck was established based on the Chinese pilot’s stature standard. The simulation and experiment results were compared to verify the validity of the model. The simulations under different period overload accelerations obtained from manikin traction aircrew escape experiment were performed to analyze the injuries of human head and neck in the processes of one shoulder traction and both shoulders traction. By an analysis of the head impact and acceleration, the simulation and experiment results are highly consistent. The results show that the head injury probability is small in the whole process, but the neck injury has remarkable increased probability at the rocket traction period in which the vertical peak acceleration load is about 15g (g here means acceleration of gravity).
