| Abstract: | A set of standard orthonormal bases for constrained multibody systems in Riemannian space are constructed by using modified Gram-Schmidt process. Generalized accelerations of the systems are decomposed with respect to the bases, new formulae to salve dynamic respondence of the systems are thus obtained. one numerical example is finally presented. |

| Keywords: | dynamic analysis multibody system Riemannian space acceleration decomposition |
