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.

Noether's theory of mechanical systems with unilateral constraints

Applied Mathematics and Mechanics, 2000
In the last twenty years, the study of Noether's theory has become a popular topic by mechanicians, and a lot of remarkable generalizations have been made. However, all these researches were limited to systems with bilateral constraints, but, in practice, the problems with unilateral constraints are more interesting.

POINTWISE BOUNDS FOR THE SOLUTION OF UNILATERAL CONSTRAINT PROBLEMS

The Quarterly Journal of Mechanics and Applied Mathematics, 1987
Upper and lower bounds to the solution at an interior point of a unilateral constraint problem for Laplace's equation in two dimensions are obtained and applied to the problem of a circular elastic membrane in contact with a rigid ellipsoid.

Buckling under unilateral constraints

International Journal of Solids and Structures, 1979
Abstract The classic variational theory for eigenvalue problems is extended so as to define the Euler critical load of a unilaterally constrained beam. The Euler load is obtained by minimising a Rayleigh quotient on a convex subset of a Hilbert space. The variational formulation also provides a method of bounding the buckling load by comparison.

Continuous control law from unilateral constraints

2008 IEEE International Conference on Robotics and Automation, 2008
The control approaches based on tasks, and particularly based on a hierarchy of tasks, enable to build complex behaviors with some nice properties of robustness and portability. However it is difficult to consider directly unilateral constraints in such a framework.
