【摘要】 针对我国弹射救生系统研制中仿真技术应用的不足,以主流的第三代弹射救生系统为仿真对象,建立了弹射救生人椅系统动力学模型及相关各子系统的数学模型,并以MATLAB\SIMULINK为工具实现了人椅系统的六自由度仿真,取得了较好的仿真效果;通过对系统重量、火箭推力、飞机姿态等设计参量的分析,可以为弹射救生系统的方案设计及验证提供技术支撑。更多还原

【Abstract】 With the 3-generation ejection seat as simulated object, the dynamical models of the ejection seat and occupant system were established, which includes every subsystem‘s mathematical model of escape system, and 6DOF trajectory simulation of the ejection seat and occupant system on SIMULINK was realized. The program of 6DOF trajectory simulation can support the conceptual design and validation of ejection system by analyzing such variables as system weight and thrust.更多还原
