Adhesive and molecular friction in tribological conjunctions [PDF]
This thesis investigates the underlying causes of friction and ine ciency within an internal combustion engine, focusing on the ring-liner conjunction in the vicinity of the power-stroke top dead centre reversal.

Multi-physics simulation of friction stir welding process [PDF]
Purpose: 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 ...

Friction Modelling in Boundary Lubrication Considering the Effect of MoDTC and ZDDP in Engine Oils
A predictive friction model has been developed in boundary lubrication conditions to understand the sensitivity of the model to molybdenum dithiocarbamate (MoDTC), a friction modifying additive and zinc dialkyldithiophosphate (ZDDP), an antiwear additive

A prediction model of flat belt slippage considering rigid-slip during power transmission
The purpose of this study is to propose an effective model for predicting the slip ratio of a belt transmission mechanism during power transmission, considering the different tensile stiffness of the drive belt.

A liquid-crystal model for friction [PDF]
Rate-and-state friction is an empirical approach to the behavior of a frictional surface. We use a nematic liquid crystal in a channel between two parallel planes to model frictional sliding. Nematic liquid crystals model a wide variety of physical phenomena in systems that rapidly switch between states; they are well studied and ...

Mathematical Model of Linear Motor Stage with Non-Linear Friction Characteristics
This paper proposes a mathematical model of a feed drive system consisting of a cylindrical linear motor and linear ball guides. The friction model consists of two components; a model for the relationships between displacement and friction force under ...

Avalanche precursors in a frictional model [PDF]
We present a one-dimensional numerical model based on elastically coupled sliders on a frictional incline of variable tilt. This very simple approach makes possible to study the precursors to the avalanche and to provide a rationalization of different features that have been observed in experiments.
