摘　　要：为满足弹射救生装置教学训练的需求,利用增强现实技术构建了弹射救生模拟训练装置。通过分析弹射救生装置的工作过程,确定了模拟训练装置的工作需求,并以此为基础搭建了硬件平台,设计了弹射救生模拟训练软件工作流程,以还原弹射救生系统的工作过程。为解决视景驱动和载荷感知等技术难题,分析了弹射过程中弹射上升、弹射离机阶段的视景特点和动载荷的特性,并分别建立了数学模型以提高系统的真实沉浸感。运行结果表明,本系统能够最大限度地还原飞机在平飞状态下的弹射救生场景;系统还原度高,对掌握整个弹射救生流程有较大帮助,能够有效纠正错误的弹射操纵动作以提高过载适应能力,有利于把握正确的弹射时机,满足弹射救生训练需求。In order to meet the needs of ejection rescue device simulation training,the ejection rescue simulation training device is constructed by using augmented reality(AR)technology.By analyzing the working process of the ejection rescue device,the work requirements of the simulation training device are analyzed.Based on this,the hardware platform is built and the ejection rescue simulation training workflow is designed to restore the working process of the ejection rescue system.In order to solve the technical problems of visual driving and load sensing,the visual characteristics of the ejection rising and ejection leaving phases and dynamic load characteristics are analyzed,and the mathematical models are established to improve the real immersion of the system.The system operation results show that it can restore the ejection trajectory and the parachute opening load of the aircraft in the horizontal flight state to the maximum extent,the system has a high degree of reduction,which is helpful to master the whole ejection rescue process,and can effectively correct the wrong ejection control action to improve the overload adaptability,which is conducive to grasp the correct ejection timing to meet the ejection rescue training demand.
