A Method for Evaluating Dynamical Friction in Linear Ball Bearings [PDF]
Sensors, 2010 A method is proposed for evaluating the dynamical friction of linear bearings, whose motion is not perfectly linear due to some play in its internal mechanism.

Closed-Form Representations of Friction
IEEE Access, 2021 The current developed friction models are basically based on the assumption of the normal forces exerted between the contact surfaces known in advance, less work has been done for closed-form (i.e., analytic) modeling in complex mechanical systems where ...

Fundamental Structure of General Stochastic Dynamical Systems: High-Dimension Case
Journal of Mathematics, 2022 No one has proved that mathematically general stochastic dynamical systems have a special structure. Thus, we introduce a structure of a general stochastic dynamical system. According to scientific understanding, we assert that its deterministic part can

Influence of Dry Friction on the Dynamics of Cantilevered Pipes Conveying Fluid
Applied Sciences, 2022 A cantilevered pipe conveying fluid can lose stability via flutter when the flow velocity becomes sufficiently high. In this paper, a dry friction restraint is introduced for the first time, to evaluate the possibility of improving the stability of ...

Dynamical Friction in dE Globular Cluster Systems [PDF]
, 2001 The dynamical friction timescale for globular clusters to sink to the center of a dwarf elliptical galaxy (dE) is significantly less than a Hubble time if the halos have King-model or isothermal profiles and the globular clusters formed with the same ...

Dynamical friction for accelerated motion in a gaseous medium [PDF]
, 2009 Dynamical friction arises from the interaction of a perturber and the gravitational wake it excites in the ambient medium. This interaction is usually derived assuming that the perturber has a constant velocity.
