Abstract

Abstract: The non-synchronization phenomenon during the deployment of the hoop truss deployable antenna is obvious in the ground test, which was caused by the damping and other factors. The multi-flexible dynamics system model was established by the absolute nodal coordinate formulation (ANCF). To analyze the non-synchronization phenomenon, the stress and the distortion were obtained during the continuous deployment of the truss. The results show that the non-synchronization is caused by the distortion and friction between the elements of the antenna. The non-synchronization phenomenon is consistent with the stress, which makes the truss endure higher load.

Key words: Absolute nodal coordinate formulation, Deployment, Non-synchronization phenomenon, Multi-flexible dynamics, Hoop truss deployable antenna
