This paper establishes the multibody dynamic model of the deployment process of a large parachute and adopts the mass-spring-damper model to simulate the suspension line and canopy. In the model, the factors of the stack sequence of the suspension line and the canopy as well as the pullout process of the bridle segments and constraint of the binding rope were considered. The model was validated by an airdrop test video. The reason for the formation of the whipping phenomenon was analyzed and validated through theoretical modeling and simulation. This paper also studies the influencing factors of the whipping phenomenon and evaluates the effect of the attached apex drogue that prevents the whipping phenomenon from forming. The research of this paper provides an analytical method to model and simulates the deployment process and the whipping phenomenon for a large parachute.
