Abstract
With the development of aerospace science and technology, small satellites have become an important part of space systems. Equipped with deployable structure as a working platform on a small satellite will broaden the function of the small satellite. Because the mass and volume of small satellites are very small, the attitude adjustment ability is limited. The dynamic characteristics of deployable structure has a great influence on the state attitude control in orbit of small satellites. This paper conducts the dynamic analysis for a single-layer deployable truss structure driven by elastic components. Through the modal analysis, the nonlinear transient dynamics analysis and the fundamental frequency measuring experiment, the dynamic characteristic of the deployable structure is investigated.
