Decomposition of Scalar Force Interactionsmposition of the force interactions leading to a classical continuous force law and a set-valued law which is expressed by a monotone step function. It is shown that the step function may be obtained by arranging unilateral primitives parallel to each other and in series, finally resulting in a comp

On The Well-Posedness of Painlevé’s Examplend dry friction. The analysed example is the wellknown Painlevé system (Painlevé, 1895). In particular we will focus on singularities of the dynamics in sliding regimes, i.e. configurations at which the contact force diverges to infinity. The problem of inconsistencies, that is configurations for wh

Dynamic Grasping Problem with Impactzed bodies. As a pilot problem we consider the possible impacts occuring during a grasping procedure by a robot hand. To this end we study the impact problem of a 3D-discretized structure. We first prove certain equivalent forms for d’Alembert’s principle, including the velocity discontinuity, and t

Experimental Investigation of Impacts with Frictions contact process must be modelled to give a realistic prediction of the physical behaviour. If the impact is so short that the movement of the bodies during contact can be neglected and the magnitudes of the contact forces exceed those of all other forces in the system, one can describe the impact

Dynamics of The Generator of The Impact Forceficiency of operation of industrial machines, or to eliminate those phenomena which are undesirable during machine operation. In the present paper a principle of operation of the impact force generator, which may be an element of the rotor of the heat exchanger has been presented. Step disturbances

Simultaneous Parametric and Internal Resonances in Systems Simulating Liquid Sloshing Impactetric and internal resonance conditions. The analytical modeling of the liquid impact forces is represented by a simple pendulum. The impact forces with the tank walls are phenomenologically described by a power function. In the absence of internal resonance, Pilipchuk and Ibrahim (1997) analyzed th

In multibody dynamics, collisions are treated as instantaneous changes of velocities and angular velocities under impulsive reactions. The problem is to determine such changes or, similarly, the
