摘　　要：为了研究物伞回收系统的运动稳定性,建立了物伞系统的五自由度动力学模型,并对其纵向和横向的运动稳定性进行理论分析,得出一些参数对系统运动稳定性的影响。对纵向和横向运动进行小扰动仿真分析,得出了其响应运动形态,其结论可作为回收系统设计的理论参考依据。In order to research the stability of the parachute-payload system, a five degree of freedom model is built, the stability of longitudinal and transverse motion is analyzed in theory, and the impact on the motion stability of some parameters is also analyzed. The simulation of the longitudinal and transverse motion in little disturbance is analyzed and the forms of the motion in response are educed, the conclusion can provide theoretical reference for the design of the recovery system.
