“…The researchers proposed that the material fatigue of the rolling contact surface is the main failure mode if a rolling element bearing is properly loaded, lubricated, installed and kept free of foreign contaminants . Over the past several decades, many probabilistic engineering life models and deterministic research life models for rolling contact fatigue (RCF) have been developed . Industrial standards, such as ISO 281 and the SKF general catalog 5000 , accept the model proposed by Lundberg and Palmgren despite its known limitations.…”

Long‐term contact fatigue analysis of a planetary bearing in a land‐based wind turbine drivetrain

This paper presents an approach for performing a long-term fatigue analysis of rolling element bearings in wind turbine gearboxes. Multilevel integrated analyses were performed using the aeroservoelastic code HAWC2, the multibody dynamics code SIMPACK, the three-dimensional finite element code Calyx and a simplified lifetime prediction model for rolling contact fatigue. The National Renewable Energy Laboratory's 750 kW wind turbine and its planetary bearing were studied. Design load cases, including normal production, parked and transient load cases, were considered. To obtain the internal bearing load distribution, an advanced approach combining a finite element/contact mechanics model and a response surface model were used. In addition, a traditional approach, the Harris model, was also applied for comparison. The long-term probability distribution of the bearing raceway contact pressure range was then obtained using Weibull and generalized Gamma distribution functions. Finally, we estimated the fatigue life of the bearing, discussed the differences of the methods used to obtain the bearing internal loads and analyzed the effects of the environmental conditions and load cases on the results. The Harris model may underestimate the inner raceway life by 55.7%, which can cause large load fluctuations along the raceways. The bearing fatigue life is very sensitive to the wind distribution and less affected by the transient and parked load cases.

Surface Integrity in Machining

View full text Add to dashboard Cite

This chapter presents an overview of the nature of the surface that results from manufacturing processes, as this nature has long been recognized as having a significant impact on the product performance, longevity and reliability. Surface alterations may include mechanical, metallurgical, chemical and other changes. These changes, although confined to a small surface layer, may limit the component quality or may, in some cases, render the surface unacceptable. A basic understanding of the changes in the condition of the surface is very much required if improvement in product quality is to be attained. Surface integrity (SI) reveals the influence of surface properties and condition upon which materials are likely to perform. It has long been known that the method of surface finishing and the complex combination of surface roughness, residual stress, cold work, and even phase transformations strongly influence the service behavior of manufactured parts as fatigue and stress corrosion.
