| Abstract: | On the basis of differential geometic theory that is used to solve differential algebraic equations, a new numericl method for dynamics of flexible multibody systems is presented, which combines differential geometric approach with backward differentiation formula. Also the validity and effectiveness are illustrated with typical examples. |
| Keywords: | dynamics of flexible multibody systems differential algebraic equations differential geometry backward differentiation formula. |
