The deployment mechanism (DM) is modeled by using Mechanical Desktop (MDT) software and analyzed by using Finite Element Analysis Package (ANSYS 11). Design and Stress analysis of DM is performed at the most critical points during its functioning. Several finite element analysis models were considered to verify the DM integrity. These analyses were correlated with static, modal and random vibration testing. The present work can help in checking the survival of the mechanism under realistic operating conditions and makes sure that it will perform well after an orbit insertion of the satellite. http://pubs.sciepub.com/ajme/1/3/2/ajme-1-3-2.pdf satellite deployment mechanism shoe brake solar Array finite element modal analysis
