摘要/Abstract

摘要： 为了保障直升机牵引救生过程中飞行员的安全,基于我国飞行员身材标准,建立了人体头颈部有限元模型。根据模拟假人在牵引救生实验中的加速度载荷数据,对单肩斜拉牵引和双肩牵引过程中的人体头颈部的损伤情况进行了仿真计算,通过与文献中的事故试验数据对比,验证了模型的可信性。结果表明,在峰值加速度(垂向)载荷约为15 g(g为重力加速度)的条件下,牵引救生过程中头部受损伤的概率小,但颈部在火箭牵引阶段受损伤的概率大。

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).

Key words: traction aircrew escape system, finite element method analysis, head and neck, injury analysis
