RISA Quantitative Structure Tribo Ability Relationship Model for Ester Lubricant Base Oils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Friction tests with point–point contact were carried out using a microtribometer to investigate the tribological characteristics of steel/steel rubbing pair immersed in 57 kinds of esters as lubricant base oils. A set ...
A Three Dimensional Quantitative Structure Tribo Ability Relationship Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The prediction of lubrication characteristics for compounds through tribological models would aid in the discovery of new lubricant additives and improved lubricant design. But until recently, the field of tribological ...
BPNN–QSTR Friction Model for Organic Compounds as Potential Lubricant Base Oils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A series of ball–disk contact friction tests were carried out using a microtribometer to study the tribological characteristics of steel/steel rubbing pairs immersed in 47 different organic compounds as lubricant base ...
Quantitative Structure Tribo Ability Relationship for Organic Compounds as Lubricant Base Oils Using CoMFA and CoMSIA
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The structures and the wear data of 47 different organic compounds as lubricant base oils were included in a comparative molecular field analysis (CoMFA) and comparative molecular similarity index analysis (CoMSIA)–quantitative ...
Influences of Design Parameters on a Double Serpentine Convergent Nozzle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Serpentine nozzles are supplied in stealth bombers and unmanned aerial vehicles (UAVs) to evidently suppress the infrared radiation signatures (IRSs) emitted by engine exhausts. It is commonly known that excessive geometric ...
Estimating Antiwear Properties of Ionic Liquids as Lubricant Additives Using a QSTR Model
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The antiwear properties of ionic liquids (ILs) as lubricant additives were studied with polyethylene glycol (PEG) used as the lubricant base oil. The quantum parameters of the ILs were calculated using a Hartree–Fock ab ...
Uncertainty Propagation and Assessment of Five-Axis On-Machine Measurement Error
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important technology of adaptive machining, on-machine measurement (OMM) is always used to measure the shape of the to-be-cut surface. Due to the multi-source errors in an OMM system, the confidence of the measurement ...
A Climatology of the Precipitation over the Southern Ocean as Observed at Macquarie Island
Publisher: American Meteorological Society
Abstract: acquarie Island (54.50°S, 158.94°E) is an isolated island with modest orography in the midst of the Southern Ocean with precipitation records dating back to 1948. These records (referred to as MAC) are of particular interest ...
Understanding Orographic Effects on Surface Observations at Macquarie Island
Publisher: American Meteorological Society
Abstract: he meteorological observations on Macquarie Island have become of increasing value for efforts to understand the unique nature of atmospheric processes over the Southern Ocean. While the island is of modest elevation (peak ...
