EXISTENCE AND WEAK STABILITY FOR A PRESSURELESS MODEL WITH UNILATERAL CONSTRAINT

, 2002
We consider a two-phase model described by a pressureless gas system with unilateral constraint. We prove weak stability and the existence of weak solutions by passing to the limit in the sticky-blocks dynamics.

Singularities of manipulators with non-unilateral constraints

Robotica, 2005
An analytical method is presented to obtain all surfaces enveloping the workspace of a general n degree-of-freedom mechanism with non-unilateral constraints. The method is applicable to kinematic chains that can be modeled using the Denavit-Hartenberg representation method for serial kinematic chains or its modification for closed-loop kinematic chains.

Optimal control of systems with unilateral constraints

Proceedings of 1995 IEEE International Conference on Robotics and Automation, 2002
Problems in robotics and biomechanics such as trajectory planning or resolution of redundancy can be effectively solved using optimal control. Such systems are often subject to unilateral constraints. Examples include tasks involving contacts (e.g., walking, running, multifingered or multiarm manipulation), and other tasks that may not involve contacts

DYNAMICS OF MULTIBODY SYSTEMS WITH UNILATERAL CONSTRAINTS

International Journal of Bifurcation and Chaos, 1999
In couplings of machines and mechanisms, backlash and friction phenomena are always occurring. Whether stick–slip phenomena take place depends on the structure of such couplings. These processes can be modeled as multibody systems with a time-varying topology.

Robots with Unilateral Constraints

IFAC Proceedings Volumes, 1997
Abstract A robot coming into any contact with its environment generates in the sense of mechanics some unilateral constraints, which - due to its unilaterality - might be dissolved again depending on the surrounding dynamics. The laws governing such situations must consider the typical complementary behavior of contacts which means, that either ...

The dynamics of systems with unilateral constraints

Journal of Applied Mathematics and Mechanics, 1984
The possibility of extending the canonical formalism to a system with ideal unilateral constraints is demonstrated. The problem of the motion of a heavy material point in a vertical plane not below a certain smooth curve is considered as an illustration.
