Extrapolation integrators for constrained multibody systems
نویسنده
چکیده
Extrapolation methods using the structure in the equations of motion of multibody systems are given in this article. The methods are explicit in the differential part and implicit in the nonlinear constraints. They admit a robust formulation in which only linear systems of equations are solved most of the time. Related methods, which are linearly implicit also in the differential part, are developed for stiff mechanical systems. Numerical results for the extrapolation code MEXX are included.

The Comparison of Direct and Indirect Optimization Techniques in Equilibrium Analysis of Multibody Dynamic Systems
The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...
متن کاملGamma-convergence of Variational Integrators for Constrained Systems
For a physical system described by a motion in an energy landscape under holonomic constraints, we study the -convergence of variational integrators to the corresponding continuum action functional and the convergence properties of solutions of the discrete Euler–Lagrange equations to stationary points of the continuum problem. This extends the results in Müller and Ortiz (J. Nonlinear Sci. 14:...
متن کاملVariational integrators for constrained dynamical systems
A variational formulation of constrained dynamics is presented in the continuous and in the discrete setting. The existing theory on variational integration of constrained problems is extended by aspects on the initialization of simulations, the discrete Legendre transform and certain postprocessing steps. Furthermore, the discrete null space method which has been introduced in the framework of...
متن کاملHybrid Complementarity Formulations for Robotics Applications
The focus of this paper is to review hybrid recursive-complementarity formulations for multibody systems characterized by a large number of bilateral constraints which are frequently encountered in robotics. Here, hybrid implies the use of complementarity contact models with recursive forward dynamics schemes. Such formulations have a common underlying structure which can be applied to multibod...

A recently developed extrapolation method for integrating the equations of motion of mechanical multibody systems is investigated. The inherent parallelism of the extrapolation scheme is used for an implementation on a transputer network. The eeciency of the parallel algorithm is demonstrated at a multibody system which is part of a mechanical printing device. Identiizierungs-, Analyse-und Entw...
