| Abstract: | Based on the mixed coordinates, a forward recursive and combinative formulation, and its software implementation for dynamics of flexible multibody systems with any tree topology are presented in the paper. The functions of the software named DAFMB, are introduced in detail. A two pendulum example is studied to illustrate computational efficiency and stability by comparison with the formulation based on Cartesian coordinates, and DAFMB may be an efficient tool of computer aided analysis for dynamics and control of flexible multibody systems. |
