【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.更多还原
