| Abstract: | Deployment kinematics and dynamics of Variable Geometry Truss(VGT) structures are analyzed systematically. The recursive formulae of kinematic analysis are presented by using con- straint equations. Employing the D'Alembert's principle in virtual work, the dynamic equations of deployable VGT are derived. All of these formulae and equations are of a computer-oriented form. A numerical example is given to show the validation of the analysis method. |
