APPROBATION OF TRIBOMETER WITH SEPARATED INPUT AND OUTPUT SIGNALS IN INVESTIGATION EXTERNAL FRICTION DYNAMICS STEEL AND BRASS MATERIALS [PDF]
Proceedings on Engineering Sciences, 2019 This investigation suggests a method used to determine the evolution of metallic wear and friction by sliding. The problem of external dynamics friction is investigated through the definition of the dynamic characteristics such as damping factor and ...

A novel friction model for predicting nonlinear friction dynamics [PDF]
International Journal of Modelling, Identification and Control, 2021 In this paper a new dynamic friction model capable of modelling observed friction dynamics is presented. The model incorporates a pre-sliding friction function with non-local memory hysteresis features. Simulations showed the model's ability to predict known friction features.

A Second-Order Dynamic Friction Model Compared to Commercial Stick–Slip Models
Modelling, 2023 Friction has long been an important issue in multibody dynamics. Static friction models apply appropriate regularization techniques to convert the stick inequality and the non-smooth stick–slip transition of Coulomb’s approach into a continuous and ...

Dynamical friction for compound bodies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 In the framework of the fluctuation-dissipation approach to dynamical friction, we derive an expression giving the orbital energy exchange experienced by a compound body as it moves interacting with a non homogeneous discrete background. The body is assumed to be composed of particles endowed with a velocity spectrum and with a non homogeneous spatial ...

Interactive Dynamic Simulator for Multibody Systems [PDF]
, 2012 We propose an interactive dynamic simulator for humanoid robots using constraint-based methods for computing interaction forces with friction. This simulator is a part of a general framework for prototyping called AMELIF and is a successful integration ...

Multi-physics simulation of friction stir welding process [PDF]
, 2010 The Friction Stir Welding (FSW) process comprises of several highly coupled (and non-linear) physical phenomena: large plastic deformation, material flow transportation, mechanical stirring of the tool, tool-workpiece surface interaction, dynamic ...

Analytical Formulation of the Jacobian Matrix for Non-linear Calculation of the Forced Response of Turbine Blade Assemblies with Wedge Friction Dampers [PDF]
, 2006 A fundamental issue in turbomachinery design is the dynamical stress assessment of turbine blades. In order to reduce stress peaks in the turbine blades at engine orders corresponding to blade natural frequencies, friction dampers are employed.

Dynamical friction in gravitational atoms
Journal of Cosmology and Astroparticle Physics, 2023 AbstractDue to superradiant instabilities, clouds of ultralight bosons can spontaneously grow around rotating black holes, creating so-called “gravitational atoms”. In this work, we study their dynamical effects on binary systems. We first focus on open orbits, showing that the presence of a cloud can increase the cross section for the dynamical ...
