In-Situ Measurements of the Piston and Connecting Rod Dynamics Correlated with TEHL-Simulation Techniques

SAE International Journal of Engines, 2017
<div class="section abstract"><div class="htmlview paragraph">High combustion pressure in combination with high pressure gradient, as they e.g. can be evoked by high efficient combustion systems and e.g. by alternative fuels, acts as broadband excitation force which stimulates natural vibrations of piston, connecting rod and crankshaft ...

Effect of Solid Particle on TEHL under Line Contact with Solid-Liquid Lubricant

Advanced Materials Research, 2012
The two infinitely long surfaces in line contact under thermoelastohydrodynamic lubrication with solid-liquid lubricants were investigated. The time-dependent modified Reynolds equation elasticity equation and the adiabatic energy equation have been formulated and solved numerically with initial conditions using multi-grid multi-level method with full ...

On the theory of time‐dependent micro‐TEHL for a non‐Newtonian lubricant in line contacts

Lubrication Science, 1996
AbstractThis paper presents a relatively complete numerical solution to time‐dependent micro‐thermoelastohydrodynamic lubrication in line contacts subjected to constant load and entraining velocity. Sinusoidal functions are employed to model the traverse roughness on contact surfaces.

A Dual Experimental/Numerical Approach for Film Thickness Analysis in TEHL Spinning Skewing Circular Contacts

Tribology Letters, 2013
Studies on the behaviour of rolling bearings show that the position as well as the loading of the rolling element at the flange roller-end contact depends on the momentum created on the roller track caused by local friction variability. This situation is characterized by a skew angle that varies within a limited range in the application influenced also

Inverse approach for the pressure, temperature, and pressure‐viscosity index determination in TEHL of line contacts

Industrial Lubrication and Tribology, 2012
PurposeThe purpose of this paper is to describe an inverse approach to estimate the pressure distribution, temperature distribution, and pressure‐viscosity index (z) in a thermal elastohydrodynamic lubrication (TEHL) line contact.Design/methodology/approachOnce the film thickness is given, the pressure distribution can be calculated using the inverse ...

Effects of Working Conditions on TEHL Performance of a Helical Gear Pair With Non-Newtonian Fluids

Journal of Tribology, 2014
A thermal elastohydrodynamic lubrication (TEHL) finite line contact model is developed for a helical gear pair lubricated with an Eyring fluid or a power-law fluid in order to investigate the effects of the working conditions. A lubrication analysis within a meshing period shows that the differences between the Eyring and Newtonian solutions mainly lie

ON THE TIME-DEPENDENT, SIMPLIFIED TEHL THEORY OF TILTING PAD BEARINGS SUBJECTED TO HARMONIC VIBRATIONS

Transactions of the Canadian Society for Mechanical Engineering, 1995
Performance of the tilting pad bearings, subjected to the harmonic vibration of the pad, is numerically analyzed. The thermoelastohydrodynamic analysis considers simultaneously the heat transfer, elastic deformation of pad’s working surface, side leakage, and the inlet pressure build-up.
