Resumen:
In this work we describe several numerical time integration methods for multibody system dynamics: an energy preserving scheme and three energy decaying ones, which introduce high frequency numerical dissipation in order to annihilate the non desired high frequency oscillations. An exhaustive analysis of these four schemes is done, including their formulation, energy preserving and decaying properties, taking into account the presence of nonlinear algebraic constraints and the incrementation of finite rotations.
