Abstract

This paper demonstrates Mechanical Desktop modelling and Finite Element Analysis of shoe brake specially designed to apply drag braking on the deployment mechanism of solar array mounted on a small satellite. Strength analysis was performed under realistic loads to the brake assembly, and the most critical points are checked. Several finite element analysis models were considered to verify the integrity of the deployment mechanism. These analyses considered the static, modal and random vibration testing to verify the safe performance of the brake after orbit insertion.
