Abstract

Abstract: The multi-bodies method with mass-spring damper model is used to analyze the parachute opening load in the rocket sled experiments. Results show that the computational model can be used to predict the opening load variation in rocket sled experiments. The computed maximum value and moment of opening load agree well with the experiment data. At the same time, the influences of fore-body mass and deploy velocity on the inflation load are analyzed. The analysis shows that in the range of 200~450 km/h, the peak value of the inflation load increases with the increase of the deploy velocity, and increases with the resistance characteristics of the parachute system. The peak of inflation load is increased with the increase of deploy velocity and the mass of fore-body, especially in the situation of lighter fore body mass. Results of this research provide preliminary scientific basis for design of parachute system.
