Symbs - Symbolical Analysis and Optimization of Multibody Systems in Matlab

For many applications of multibody systems the symbolic equations of motion are useful, but in most commercial multibody programs the dynamic behavior is not formulated as an explicit function and not available symbolically for the user. Within this paper the Matlab program Symbs is introduced. By using the Matlab Symbolic Toolbox the modelling of the multibody system is done symbolically, while offering different numerical possibilities for the analysis and optimization of the system. After an explanation of the structure of Symbs, the modelling and some possibilities for the analysis and optimization of a mechanical system are presented.
