| Abstract: |
| Supposed Cartersian coordinate of joint assumed as unknown variables, and dynamic equations of motion are formulated herein for deployable space truss structures. Geometric constraint equations, relevant Jacobi matrices and derivatives are developed for three classes of holonomic geometric constraint respectively. The basis of null space and M\|P generalized inverse are abtained through singular value decomposition algorithm for constraint Jacobi matrices. Using matrix reduction technique, dynamic equations of motion are thus established for constrained dynamic system. Numerical method is developed, and the algorithm proves effective for deployable truss structures. |
