A Topology Based Approach for Exploiting Sparsity in Multibody Dynamics
by Dan Negrut , Radu Serban , and Florian A. Potra December, 1995 Abstract In the present paper a new approach for solving for the accelerations and Lagrange multipliers when integrating multibody systems in descriptor form is given. When solving for these unknowns, the coefficient matrix of the linear system to be solved has the particular form of an optimization matrix. Due to the conectivity...
متن کاملSpatial Operator Algebra for Multibody System Dynamics 1
This paper describes a new spatial operator algebra for the dynamics of general{topology rigid multibody systems. Spatial operators allow a concise and systematic formulation of the dynamical equations of motion of multibody systems and the development of e cient computational algorithms. Equations of motion are developed for progressively more complex systems: serial chains, topological trees,...

متن کاملMultibody graph transformations and analysis: Part I: Tree topology systems.
This two-part paper uses graph transformation methods to develop methods for partitioning, aggregating, and constraint embedding for multibody systems. This first part focuses on tree-topology systems and reviews the key notion of spatial kernel operator (SKO) models for such systems. It develops systematic and rigorous techniques for partitioning SKO models in terms of the SKO models of the co...
متن کاملStatic Analysis of Large-Scale Multibody System Using Joint Coordinates and Spatial Algebra Operator
Initial transient oscillations inhibited in the dynamic simulations responses of multibody systems can lead to inaccurate results, unrealistic load prediction, or simulation failure. These transients could result from incompatible initial conditions, initial constraints violation, and inadequate kinematic assembly. Performing static equilibrium analysis before the dynamic simulation can elimina...
