Finite Element of Static Contact between Rolling Element and Raceway of Cageless Ball Bearing
Journal of Harbin University of Science and Technology, 2022 At present, scholars at home and abroad have paid attention to the improvement of bearing capacity and lightweight due to the removal of cage, but the theoretical research on rolling element contact is less.The principle of adding local variable speed ...

Normal contact stiffness model considering 3D surface topography and actual contact status [PDF]
Mechanical Sciences, 2021 A normal contact stiffness model considering 3D topography and elastic–plastic contact of rough surfaces is presented in this paper. The asperities are generated from the measured surfaces using the watershed segmentation and a modified nine-point ...

A discrete contact model for crowd motion [PDF]
, 2009 The aim of this paper is to develop a crowd motion model designed to handle highly packed situations. The model we propose rests on two principles: We first define a spontaneous velocity which corresponds to the velocity each individual would like to ...

Modeling the Contact Mechanics of Hydrogels [PDF]
Lubricants, 2019 A computationally lean model for the coarse-grained description of contact mechanics of hydrogels is proposed and characterized. It consists of a simple bead-spring model for the interaction within a chain, potentials describing the interaction between monomers and mold or confining walls, and a coarse-grained potential reflecting the solvent-mediated ...

A crack-like notch analogue for a safe-life fretting fatigue design methodology [PDF]
, 2003 Various analogies have recently been proposed for comparing the stress fields induced in fretting fatigue contact situations, with those of a crack and a sharp or a rounded notch, resulting in a degree of uncertainty over which model is most appropriate ...

Development of a Contact Force Model Suited for Spherical Contact Event
Actuators, 2023 The stiffness coefficient suited for a spherical contact body is developed by means of a contact semi-angle based on Steuermann’s theory. The new static contact force model is close to the results of FEM when the index of the polynomial is equal to 2 ...
