Dynamics Study on Human Upper Limbs Multi-Body System in Ejection Escaping

摘要：

In the course of ejection escaping, high-speed airflow might blow human body and make upper limbs swing, it could injure arm easily. Based on the dynamics theory of multi-body system, this paper lias built human upper limbs predigestion modeling, coordinates, coordinate conversion matrixes and so on using Kane method. We have studied the running rule of arms swing, analyzed the basic action forces of two kinds of basic attitudes (grasping the armrest and center draw ring) at ejection. The conclusion is proved that both hands pulling center draw ring is saver than holding armrest as ejecting. This research plays an important part in ensuring the planes flight speed, designing restraint units and studying the arms injury theory as ejecting.
