目的拦阻着舰会产生较大的持续性载荷,给飞行员的生理健康和操控工效带来不利影响,同时人体各部位的运动有可能导致它们与座舱及其内置设备碰撞,有必要评估其中的安全隐患。方法使用已建立的包含刚性座椅模型第5,50,95共3种百分位,HybridⅢ假人有限元模型以及六点式背带约束系统的多刚体-有限元混合人椅背带系统动力学模型开展动力学仿真,评估人体头部和四肢在典型拦阻着舰过程中的运动范围。结果采用文献中公开的典型拦阻着舰过程飞机座椅底部加速度曲线作为输入条件,获得典型拦阻着舰过程中3种不同百分位假人头部、手部和足部的位移数据。结论本文仿真数据可以为改进飞行员背带约束系统和优化座舱仪表布布局提供支持。
The purpose of blocking the ship will have a large sustained load, which will adversely affect the physiological health of pilots and the control efficiency. Meanwhile, the movement of various parts of the human body may cause them to collide with the cockpit and its built-in equipment. It is necessary to evaluate the safety Hidden trouble. Methods The kinematic model of the multi-rigid-finite element hybrid chair straps system has been established, including the 3, 5, 50 and 95 rigid seat models, the Hybrid Ⅲ dummy finite element model and the 6-point strap restraint system Kinetic simulation is conducted to assess the range of motion of the human head and limbs during a typical blockage of the craft. Results The displacement data of the head, hand and foot of the three types of percentiles were intercepted and blocked by the typical acceleration curve of the bottom of the aircraft seat blocker in the process of landing. CONCLUSIONS The simulation data provided in this paper can be used to improve the pilot strap restraint system and optimize the cockpit dashboard layout.
