摘　　要：建立了物伞回收系统固连和铰接时的平面刚体运动简化模型,针对某型号物伞回收系统进行了动力学仿真。分析了物伞初始角度一致和呈剪刀状时的物伞系统运动形态及其稳定性,分析了气动阻尼力矩对物伞系统钟摆运动稳定性的影响,其结论可为降落伞回收系统的运动形态和稳定性分析提供重要参考。The simple planar motion model of the parachute-payload system was built when the hinge point was fixed or free, and then the model was applied for simulating a type of parachute-payload system. The motion states and stability were analyzed when the initial conditions were consistent or scissors, and the influence of the dynamic damp to the motion stability ofpendulum was analyzed. The conclusion provides an important reference for the analysis to the motion states and stability of parachute-payload system.
