Dynamic Analysis of Landing Impact for Deep Space Reentry Capsules

Abstract

Firstly the finite element model including the deep space reentry capsule and landing bed for dynamic analysis of landing impact is established.Then the parameters of the landing bed are calibrated according to the experimental data of Shenzhou spacecraft.The landing impact of deep space reentry capsule is simulated and analyzed by using LS-DYNA.The landing attitude change,the stress distribution,the acceleration response curves of the key point and the impact energy absorption are got according to the simulation and analyses of the landing impact in the typical working conditions.These results can provide reference to the structural optimization,the landing attitude selection and the study to ground test for deep space exploration reentry capsules.
