| 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. |
