Sliding Contacts in Planetary Magnetospheres

Fuzzy Logic Control for Grasping 3D Objects with Sliding Contacts

The overwhelming complexity of the grasping process and imprecise knowledge about articulated robot hand systems leads to a certain control problem. In order to solve these problems, the paper proposes a new design of fuzzy control approach for two fingered robot hand, which is able to control simultaneously grasping and slipping of 3D fragile objects in unstructured environment. In this contex...

Sliding Contacts and the Dynamics of Magnetic Tape Transport

DINAME 2013 - Simulation of Dynamic Instabilities Induced by Sliding Contacts

When dealing with complex mechanical systems that include sliding contact, it is necessary to account for the coupling between the dynamic behavior of the system and the local behavior at the contact. A particular consequence of interaction between system dynamics and contact behavior is the occurring of vibrational instabilities of the mechanical system, induced by the frictional contact. The ...

Stability of rigid-body dynamics with sliding frictional contacts

The use of rigid body models during frictional contact i s often justified by proving the existence of a unique solution to the forward dynamic equations. The implicit assumption here is that the contact forces so obtained are stable. In this paper, the rigid-body assumption is relaxed and bodyto-body contacts are modeled using springs and dampers. A singular perturbation analysis reveals addit...

Friction models for sliding dry, boundary and mixed lubricated contacts

Friction, lubrication, and wear have a strong influence on the performance and behavior of mechanical systems. This paper deals with different friction models for sliding contacts running under different conditions. The models presented are suited to different situations, depending on the type of contact, running conditions, and the behavior of interest. The models will be discussed from simula...
