Estimating friction coefficient using generative modelling

2023 IEEE International Conference on Mechatronics (ICM), 2023
It is common to utilise dynamic models to measure the tyre-road friction in real-time. Alternatively, predictive approaches estimate the tyre-road friction by identifying the environmental factors affecting it. This work aims to formulate the problem of friction estimation as a visual perceptual learning task.

Effect of temperature on the frictional behavior of 18CrNiMo7-6 under lubrication

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2022
In the process of gear meshing, the tooth surface will produce friction heat, which will in turn act on the friction coefficient. The temperature does not directly affect the friction coefficient of the gear tooth surface, but indirectly through ...

Friction dependence of shallow granular flows from discrete particle simulations [PDF]

, 2011
A shallow-layer model for granular flows is completed with a closure relation for the macroscopic bed friction or basal roughness obtained from micro-scale discrete particle simulations of steady flows. We systematically vary the bed friction by changing

A constant friction coefficient model for concave friction bearings

Journal of Science and Technology in Civil Engineering (STCE) - NUCE, 2020
This paper develops a constant friction coefficient model that best represents a velocity-dependent friction model for predicting structural response of buildings isolated with concave friction bearings. To achieve this goal, the effect of friction model on structural response of three hypothetical isolated buildings with different number of stories ...
