Combined with the modeling of a perimeter truss-type deployable antenna, the general layout of this type of antenna is introduced, and the storage mechanism and design essentials are introduced. Then, a practical and effective mathematical algorithm is proposed to effectively construct the constrained equation and its Jacobian matrix. The generalized inverse matrix method is used to analyze the movement process of the surrounding expandable truss. The mechanism of the friction in the unfolding process is studied and the dynamic model is developed. Dynamic analysis of the truss deployable antenna structure considering friction. The simulation program is compiled for example analysis, which verifies the validity of the analysis method.
