摘　　要：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。Objective Sustained acceleration during arrested landing will bring adverse influences to the health and the operation performance of the pilots. During this typical process,the motion ranges of the head,the arms and the legs may be large enough to cause collision with the cockpit or the equipment. Methods Dummybelt-seat systems containing dummies of different sizes were built to investigate the motion ranges of different dummies during the typical arrested landing process. The system model contained the rigid seat model,the P5,P50 and P95 dummies,and the six-point belt system. Results Typical arrested landing acceleration at seat base from literature was used as the boundary condition for the numerical study. The motion ranges of the head,the right hand and the right feet of different dummies were obtained. Conclusion Motion ranges obtained in this research may provide basic support for the design modification of the current belt system as well as the arrangements of equipment in the cockpit.
