Abstract: In this paper,the analysis of the nonlinear dynamics of the pin jointed space structures with Harmonic Balance Method and Poincare Map Method is discussed.The experimental results of space deployable structure demonstrate the nonlinearities of the structure caused by the gap between joints.
