| Abstract: | A simulation model for solar array ground deployment and locking is proposed with the combination of ADAMS and PATRAN/NASTRAN,based on the ADAMS’s function of dynamics analysis of the flexible body.The flexibility of yoke and panels is considered at the beginning of the deployment.Concerning all the ground factors,the ground deployment and locking process is simulated constantly,and the dynamics properties,such as the impact load on solar array drive assembly,are obtained.Ground experiment has demonstrated effectiveness of the proposed approach.Then,the simulation results of solar array space deployment and locking are presented.Finally,the effects of the air resistance,the friction of the suspension system and other factors on the impact load are investigated with the simulation model. |
