Comparison Between the Absolute Nodal Coordinate Formulation and Incremental Procedures

摘要: Abstract : Many flexible multibody applications are characterized by high inertia forces and motion discontinuities. Because of these characteristics, problems can be encountered when large displacement finite element formulations used in the simulation systems. In this investigation, performance two different analysis systems is investigated. These incremental corotational procedure proposed Rankin Brogan nonincremental absolute nodal coordinate formulation recently proposed. It demonstrated investigation that limitation resulting from use rotations lead to even very simple considered. The formulation, on other hand, does not employ infinitesimal or rotation coordinates leads a constant mass matrix. Despite fact complex expression for elastic forces, results presented study, surprisingly, demonstrate such efficient static as compared procedure. excellent dynamic attributed exact representation rigid body element.
