Dynamics of Deployment Mechanism for 1 Meter Resolution Space Telescope

Deployable telescope remain in stowed position in payload fairing of launch vehicle and deployed in orbit to its final form. Development of deployment mechanism is carried out to achieve 100 micron accuracy in separation. Dynamic analysis of Deployment Mechanism is carried out to estimate desired value of stiffness of torsion spring for complete deployment and damping factor of damper to avoid shock at the end of deployment. Actual two link rigid model and flexible model are prepared using MSC ADAMS tool. Dynamic analysis is carried out to estimate Deployment time, joint angle and angular acceleration for link-1 and link-2.
