摘要：

Based on the finite element thought, a multistage, multi-finite-element and multi-freedom dynamic model of the deployment process of a large parachute was built. The effects of the attached apex drogue and peel off band on the phenomenon of bull whipping formed after the deployment process of the main parachute were studied through simulation. The analysis was focused on the comparison of shape movements of canopy, velocity of bull whipping and distance of departure with or without the attached apex drogue. The conclusion can provide theoretic help for the engineering design department in designing, improving and using the large parachute.
