Abstract
Development of space solar power station technology has important strategic significance. Limited by the transport capability of launch vehicles, a truss mechanism with three-dimensional volume expansion is proposed. Through comparative analysis of various schemes, the basic components of deployable truss are constructed. On the basis of driving principle, kinematics analysis of deployable truss is carried out, which verified the feasibility of driving scheme. Based on the principle of energy equality, equivalent model of truss continuous beam is established, and a theoretical analysis of kinematic characteristics is made. At last, a prototype of scaling principle has been developed, and the expansion test, stiffness tests and dynamic test were carried out. The results show that the deployable truss has larger folding ratio and lighter weight, and reducing hinge clearance is the key to improve system stiffness.
