RISDiffering Impacts of Black Carbon and Sulfate Aerosols on Global Precipitation and the ITCZ Location via Atmosphere and Ocean Energy Perturbations
Publisher: American Meteorological Society
Abstract: AbstractThis study explores the effects of black carbon (BC) and sulfate (SO4) on global and tropical precipitation with a climate model. Results show that BC causes a decrease in global annual mean precipitation, consisting ...
Analysis of Static and Dynamic Characteristic of Hydrostatic Spherical Hinge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new hydrostatic spherical hinge is developed in this paper to provide a large load capacity. The static and dynamic Reynolds equations in spherical coordinate system for incompressible Newtonian fluid were established ...
Analysis of the Static Characteristics of a Self Compensation Hydrostatic Spherical Hinge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This technical brief presents a new selfcompensation hydrostatic spherical hinge to provide a large load capacity. The hinge consists of an upper part with selfcompensation and a lower part with orifice restrictors. A ...
Investigation of the High Speed Rolling Bearing Temperature Rise With Oil-Air Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The oil-air lubrication system has been widely used for rolling ball bearing. However, as the rotation speed increases, the temperature rise will increase dramatically, resulting in shortening ...
Cavitation Erosion Resistance of Silicified Graphite by Liquid Silicon Penetration Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This technical brief studied the cavitation erosion behavior of the silicified graphite. The phase constituents, surface microstructure, and chemical compositions of silicified graphite were examined by using X-ray diffraction ...
Dynamic Analysis of a Motorized Spindle With Externally Pressurized Air Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to investigate the dynamic characteristics of a motorized spindle with externally pressurized air bearings. The externally pressurized air bearings consist of a journal bearing and a double pad ...
Dynamic Design of a High-Speed Motorized Spindle-Bearing System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This technical brief presents a dynamic model based on the traditional transfer matrix method (TMM) and Jones–Harris nonlinear rolling bearing model to study the effects of the extended structure ...
Research on Thermal Characteristics of Spindle System With Tilting Pad Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spindles with tilting pad bearings have been widely applied in machine tools due to their high running precision. However, friction power loss will increase dramatically when the bearing runs at a higher speed. So far, ...
Dynamics of Flywheel Energy Storage System With Permanent Magnetic Bearing and Spiral Groove Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Developing a flywheel energy storage system (FESS) with permanent magnetic bearing (PMB) and spiral groove bearing (SGB) brings a great challenge to dynamic control for the rotor system. In this paper, a pendulum-tuned ...
Study of the Stiffness Matrix of Preloaded Duplex Angular Contact Ball Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the stiffness characteristics of preloaded duplex angular contact ball bearings. First, a five degrees-of-freedom (5DOF) quasi-static model of the preloaded duplex angular contact ball bearing is established ...
