摘 要:
为分析伞系统在稳定下降阶段运动稳定性,建立了5自由度的物伞模型,通过仿真发现具有不同气动力形式的物伞系统,其摆动情况有明显差异,并着重分析了气动力参数对物伞系统的摆动角度、频率的影响。[著者文摘]

Abstract:
A five degrees of freedom model of the parachute-load system is performed to analyze its dynamic stability in steady descent, and the distinct differentia of the oscillations are found under different aerodynamic forces through a simulation, the influence of aerodynamic parameters on the system's oscillation angle and frequency is discussed emphatically.[著者文摘]
