Symbolic Computations in Multibody Systems [PDF]

, 1994
Symbolic formula manipulation has proven to be an efficient tool in the dynamical analysis of multibody systems. A multibody system data base is introduced and its implementation using a CAD-3D-software is shown. Starting from the data base the equations of motion are generated by a coordinate partitioning approach combined with the projection ...
