Book Synopsis Modeling and Analytical Methods in Tribology by : Ilya I. Kudish
Download or read book Modeling and Analytical Methods in Tribology written by Ilya I. Kudish and published by CRC Press. This book was released on 2010-07-20 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving our understanding of friction, lubrication, and fatigue, Modeling and Analytical Methods in Tribology presents a fresh approach to tribology that links advances in applied mathematics with fundamental problems in tribology related to contact elasticity, fracture mechanics, and fluid film lubrication. The authors incorporate the classical tenets of tribology while providing new mathematical solutions that address various shortcomings in existing theories. From contact interactions to contact fatigue life, the book connects traditionally separate areas of tribology research to create a coherent modeling methodology that encompasses asymptotic and numerical techniques. The authors often demonstrate the efficacy of the models by comparing predictions to experimental data. In most cases, they derive equations from first principles. They also rigorously prove problem formulations and derive certain solution properties. Solutions to problems are presented using simple analytical formulas, graphs, and tables. In addition, the end-of-chapter exercises highlight points important for comprehending the material and mastering the appropriate skills. Unlocking the secrets that govern the physics of lubricated and dry contacts, this book helps tribologists on their quest to reduce friction, minimize wear, and extend the operating life of mechanical equipment. It provides a real-world industrial perspective so that readers can attain a practical understanding of the material.
Book Synopsis Automotive Lubricants Reference Book by : Arthur J. Caines
Download or read book Automotive Lubricants Reference Book written by Arthur J. Caines and published by John Wiley & Sons. This book was released on 2004 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: The automotive lubricants arena has undergone significant changes since the first edition of this book was published in 1996. Environmental concerns, particularly reagarding improvement of ar quality have been important in recent years, Reduced emmissions are directly related to changes in lubricant specifications and quality, and the second edition of the Automotive Lubricants Reference Book reflects the urgency of such matters by including updated and expanded detail. This second edition also considers the recent phenomenon of increased consolidation within the oil and petroleum additive arenas, which has resulted in fewer poeple for research, devlopment, and implementation, along with fewer competing companies. After reviewing the first edition the authors have fully reviewed and updated the information to fit in with the changes in technology and markets. Chapters include, Introduction and Fundamentals Constituents of Modern Lubricants Crankcase Oil Testing Crankcase Oil Quality Levels and Formulations Practical Experiences with Lubricant Problems Performance Levels, Classification, Specification, and Approval of Engine Lubricants. Other Lubricants for Road Vehicles Other Specialized Oils of Interest Blending, Storage, Purchase, and Use Safety Health, and the Environment The Future.

Book Synopsis Low-Temperature Rheological Response of Fresh Versus Used Oils Using the Scanning Brookfield Technique by : Gregory C. Miiller
Download or read book Low-Temperature Rheological Response of Fresh Versus Used Oils Using the Scanning Brookfield Technique written by Gregory C. Miiller and published by . This book was released on 2013 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rheological measurements of modern engine oils have been shown to be important, particularly when determining their low-temperature pumpability. Historical and recent field failures dictate that testing fresh and used oils is critical in determining whether oil is free of the potential to form a structure reported as gelation. This paper presents studies utilizing the scanning Brookfield technique as a powerful tool to analyze both fresh and used engine oils.

Book Synopsis Viscometric Temperature Sensitivity of Engine Lubricants at Low Temperature and Moderately High Shear Conditions by : C. Patrick Maggi
Download or read book Viscometric Temperature Sensitivity of Engine Lubricants at Low Temperature and Moderately High Shear Conditions written by C. Patrick Maggi and published by . This book was released on 2007 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-temperature viscosity of engine oils is a key indication of a lubricant's capacity to provide wear protection during starting and subsequent operation of an engine. Some 40 years ago the Cold Cranking Simulator (CCS) was developed to measure the low-temperature viscosity of engine oil with viscometric conditions similar to a starting engine. The importance of cranking viscosity has grown since the test was originally developed and is now one of two low-temperature viscosity measurements that define the SAE grades for engine oils. Previous studies evaluating viscosities determined by the CCS have focused on test precision and correlation to engine starting performance. This study evaluates the effects small offsets from the indicated temperature have on the measured apparent viscosity of engine oils. Interest in this topic was driven by the observation that some engine oil formulations have abnormally high variation in viscosity. All the low-temperature viscosity measurements were made in the CCS in accord with ASTM D 5293-04. A small temperature offset was achieved by adjusting the CCS temperature probe calibration so that the indicated test operating temperature was offset from the true temperature. The viscosity data were collected using automatic thermoelectrically cooled CCS instruments. Comparative viscosity data were collected on instruments using cold methanol to control the sample temperature. The oil samples in this study consisted of base oils, a selection of commercial engine oils of the API performance category SL, recent ASTM Interlaboratory Crosscheck Program (ILCP), and from the Low Temperature Engine Performance (LTEP) study which was conducted in the 1990s. The LTEP oils are of an earlier performance category and thus have a different composition than either the API SL commercial engine oils or the ASTM ILCP program oils. Results of this study show that when the CCS stator and sample are warmer than the indicated temperature, the measured viscosities are higher than when the viscosity is measured at the correct (true) temperature. As would be expected, the opposite response is seen when the offset is in the opposite direction. This response to the temperature offset is opposite of what would be traditionally expected--lower temperatures typically result in higher measured viscosities. As seen in the study, this is a result of the way the instrument is calibrated and not a fluid anomaly. Some of the API SL oils exhibited more than a 5 % change in measured viscosity from a 0.5°C shift in temperature. Base oils and synthetic formulations only had a change of around 1 % due to a 0.5°C shift in temperature. The samples of API SG oils have temperature sensitivity lower than the API SL oils tested. This study compares data obtained on instruments using two different methods of controlling sample temperature. For the samples evaluated in this program, the data indicated no relative bias between the two methods (thermoelectric and cold methanol) of stator temperature control.
