Download or read book Applying Finite Element Analysis to Determine the Subsurface Stress and Temperature Gradient in Highly Loaded Bearing Contacts written by Nelson H. Forster and published by . This book was released on 2017 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stress and temperature gradient in the classic subsurface stress zone for rolling contact fatigue is determined using finite element analysis. The solution applies boundary conditions based on experimental life testing of 208 size ball bearings. Two thrust loads are considered to produce elastic Hertzian contact stress values of 3.10 and 3.58 GPa. X-ray diffraction data were used to superimpose the residual stress for a case carburized M50 NiL as compared to through hardened M50 material. An updated version of the Computer Optimized Ball and Roller Bearing Analysis, or COBRA, bearing analytical code was used to determine the heat load from friction and oil churning loss in the bearings. The effect of hybrid bearings with metal rings and silicon nitride rolling elements versus all metal bearings is considered in the thermal solution and is notable. Results of the stress and temperature gradient found in the bearings are used to provide a qualitative assessment of the microstructural damage found in experimental bearing testing. The results provide a foundation for a more comprehensive bearing rolling contact fatigue life model.

Download or read book A Practical Tool for the Determination of Surface Stresses in Railroad Bearings with Different Contact Geometries and Load Conditions Using Finite Element Analysis written by Michael Allan Mason and published by . This book was released on 2014 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The connection between contact geometry and fatigue in tapered roller bearings utilized in the railroad environment is still of interest. Roller bearings for railroad applications are typically precision ground with crowned contact geometries to prevent edge loading of components. This normally results in completely elastic Hertzian contact stresses under standard railcar loads. However, under extreme load conditions, detrimental edge loading has been known to occur. It is proposed to develop a tool, using finite element analysis, that can be utilized to optimize complex raceway crown geometries for severe applications. A successful implementation of this tool is presented and validated using proven Hertzian contact theory. Correlation within 5% of the ultimate surface and subsurface stress magnitudes, using finite element modeling, in contrast with proven contact theory is achieved. In addition, analyses of other load conditions and contact geometries in order to illustrate the practical application of the tool are exhibited.
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

Download or read book Modification of Standard Load Life Equation Used for Designing Rolling Element Bearings written by Nikhil Dnyaneshwar Londhe and published by . This book was released on 2014 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since twentieth century, bearing manufacturers have sought to predict the fatigue endurance capabilities of rolling element bearings. The first generally accepted method to predict bearing fatigue life was published in 1940s by Lundberg and Palmgren (LP). The load life exponents used in the LP model were determined based on statistical analysis of the experimental data which was generated in 1940s. Hence this LP model tends to under predict bearing fatigue lives for modern bearing steels. As a part of thesis research, Elasticity and Statistical Analysis were performed to correct for bearing fatigue life under prediction. It has been reported that at subsurface depths gradient in material properties exists for case hardened steels. Study show that 10% decrease in elastic modulus results in 38.66% percent improvement in bearing fatigue life prediction. Therefore, to account for this fact one more modification factor should be provided in standard load life equation. Based on the bearings endurance data reported in the literature, validation analysis of basic LP formula was also performed to calibrate the values of load life exponent for rolling element bearings. Results indicate that to best represent the observed experimental data the load life exponent for ball bearings should be corrected to 4.27 with 68.2% confidence bounds as [3.15, 5.37], against current value of 3, and for roller bearings it should be corrected to 5.66 with 68.2% confidence bounds [4.42, 7.26] as against the current value of 3.33. Hence there is need to modify standard load life equation used for bearings design.
