Singularities in differential‐algebraic systems with unilateral constraints

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1998
AbstractInequality (unilateral) constraints may introduce various types of singularities in differential‐algebraic systems ([5]). In the present paper we consider contact conditions that are formulated as unilateral constraints for position and velocity coordinates in a mechanical multibody system.

Cooperative manipulation with unilateral constraints

2011
Cooperative manipulation provides multiple robots the capability to perform tasks that are difficult or even impossible to be executed by a single manipulator. Among these tasks are, for instance, carrying heavy or large payloads, conducting multi-part assembly, and handling of flexible objects. If a large object with no special features (e.g.

Jourdain's principle for unilateral constrains

Acta Mechanica, 1986
The present paper deals with Jourdain's principle for unilateral constraints, depending on the velocities, written as a hemivariational inequality, so that it is possible to treat very general constraints. The difference from bilateral restrictions is discussed, and it is shown why it is not possible to describe rigid unilateral constraints with the ...

Nonideal unilateral constraints in impulsive mechanics: A geometric approach

Journal of Mathematical Physics, 2008
We use the differential geometric framework of the first jet bundle of the classical space-time bundle to study the impulsive behavior of a mechanical system with a finite number of degrees of freedom subject to nonideal unilateral constraints. We show that this framework allows deeper insights on the concepts of nonideal constitutive characterization ...
