The Determination of Stresses in Rolling-Contact Elements

Journal of Lubrication Technology, 1967
Stress patterns in lubricated rolling-contact elements have been computed from surface pressures and temperatures between pairs of rolling disks, both cylindrical or both crowned, measured by means of evaporated surface transducers. The maximum mechanical shearing stresses computed for both cylindrical and crowned disks proved to be nearly equal to ...

Contact Stresses in Rolling Bearings

2016
The Hertzian pressure (normal stress) in the contact zone between the ball/roller and raceways causes a plastic deformation of the ball/roller contour. In the contact area, the oil-film thickness is nearly constant at the height h c and reduces to the height at h min at the outflow of the contact zone (cf. Chap. 4). The Hertzian pressure p H in the oil

THERMAL STRESS OPTIMIZATION IN METAL ROLLING

Journal of Thermal Stresses, 1997
It is known that internal pressure in rolls has an advantageous effect upon the fatigue life of the rolls. To investigate and optimize this effect, transient and steady-state temperature and thermal stress distributions were evaluated in rolls of metal rolling machines heated over the rolling region.

The Analysis of the Stress and Strain in Skew Rolling

Advanced Materials Research, 2012
In this paper, three-dimensional finite-element model for the skew rolling (helical-groove rolling) process has been used to characterize the workpiece material stress,strain and deformation behavior. Particular attention has been paid to representative cross section and the center, edge and mid-radius points of the ...

Research of contact stresses during rolling

2023
The research provides a methodology and results of experimental research of contact stresses in the nonstationary process of strip rolling, i.e., the rolling with an increasing rear tension before it slips in the rolls. There is used a polarization-optical modeling method.

Residual Stress Analysis in Rolling Contact

1993
Based on a stress invariant hypothesis and a stress/strain relaxation procedure, an analytical approach is developed for approximate determination of residual stresses and strains in elastic-plastic rolling contact. It is shown that for the line contact problems, the proposed method provides residual stress results comparable to published results ...
