Analysis of wear-fatigue damage and modification of compressor bearings

Journal of Friction and Wear, 2007
Wear-fatigue damage of two-layer (babbitt, bronze) bushings of piston compressor bearings are analyzed. The factors generating fretting wear and fatigue cracking are analyzed. The stress-strain state of a multimodule bushing of the standard and new designs (with auxiliary strengthening by a steel layer) has been calculated with the intent of modifying ...

Analysis of relationships governing wear fatigue damage. Report 1

Strength of Materials, 1995
Wear-fatigue damage is classified and described. The main terms of tribometry are given. Complex damage is analyzed from the dialectic position and Wohler curves in fatigue (mechanical), fretting fatigue, frictionmechanical, and contact-mechanical fatigue is schematized.

Analysis of relationships governing wear-fatigue damage. Report 2

Strength of Materials, 1995
The main results of investigations of direct (effect of the friction and wear processes on the variation of the fatigue resistance characteristics) and reversed (effect of cyclic stresses on intensification of wear) effects are presented. The diagram of limiting states of the force systems characterized by complex-wear-fatigue-damage is analyzed.

Active Systems. Wear-Fatigue Damage

2005
The active system is any mechanical system that reacts to and transmits the alternating workload with simultaneous occurrence of the friction process with its any manifestation: in sliding, rolling, slippage, impact, etc. Some typical examples of the system are the following: the shaft /hub (of the gear wheel, the flywheel, etc.) with the stationary or

Effects of Wheel Materials on Wear and Fatigue Damage Behaviors of Wheels/Rails

Tribology Transactions, 2019
Rolling contact fatigue (RCF) and wear are inevitable problems for wheels and rails. Recently, increasing vehicle speeds and axle loads have led to the need for an increase in the hardness of the wheel.

INFLUENCE OF CROSSING WEAR ON ROLLING CONTACT FATIGUE DAMAGE OF FROG RAIL

Facta Universitatis, Series: Mechanical Engineering
The damage of the frog rail significantly affects the wear of the crossing rail and restricts the passing speed of the train. A geometric 3D modeling of the vehicle passing through the crossing center is particularly concerned with the cumulative wheel ...

Immature bovine cartilage wear is due to fatigue failure from repetitive compressive forces and not reciprocating frictional forces.

Osteoarthritis and Cartilage, 2023
OBJECTIVE Wear of articular cartilage is not well understood. We hypothesize that cartilage wears due to fatigue failure in repetitive compression instead of reciprocating friction.

A review on fretting wear/fatigue behavior, protective measures, and application examples of typical alloy materials

Proceedings of the Institution of mechanical engineers. Part J, journal of engineering tribology
As fastening structures are widely used in mechanical equipment and components, and fretting wear/fatigue often occurs in fastening structures. And fretting wear/fatigue significantly reduces the service lifetime of key components due to its small ...

Fretting wear-fatigue study for tribologically-induced damage in simple and complex geometries

2013
This thesis presents the development of a computational and experimental methodology for predicting fretting wear-fatigue interaction in simple and complex geometries, specifically targeting the taper-lock assembly in modular hip implants. Nonlinear continuum damage mechanics is first coupled with fretting fatigue analysis.
