Parallel Iterative Algorithm for Constrained Multibody Systems in Mechanics
This paper introduces a new family of Second-order methods for solving the index-1 DAEs of motion for flexible mechanism dynamics.These methods,which extend the a-methods for ODEs of structural dynamics to DAEsConvergence and stability is given and verifies that the DAEs a-methods introduce no addition oscillations and preserve the stability of the underlying ODEs.Convergence of the Newton iteration,which can be a source of difficulty in solving nonliner oscillatory systems with large stepsizes,is achieved via a coordinate-split modification to the Newton iteration.
