RISTheoretical Condition for the Cxy=Cyx Relation in Fluid Film Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computer program for calculating dynamic coefficients of journal bearings is necessary in designing fluid film journal bearings and an accuracy of the program is sometimes checked by the ...
Earthquake-Induced Instability of a Rotor Supported by Oil Film Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of seismic waves on the stability of a Jeffcott rotor supported by oil film bearings is investigated by calculating loci of the centers of the journal and the disk using the ...
A New Apparatus for Estimating Die Profile Friction in Deep Drawing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new deep-drawing apparatus is developed for examining the compatibility problem between the tool and the workpiece material in metal forming. The die consists of two parts divided coaxially, ...
Energy Partition in Conventional Surface Grinding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to estimate the energy partition to the workpiece in surface grinding, the temperatures at various depths from the ground surface of the workpiece were measured using the PVD (physical ...
Temperature Measurement of Workpieces in Conventional Surface Grinding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Temperature at various depths from the ground surface in workpiece is measured accurately by using the newly developed PVD film method, in which a thin film deposited on the workpiece is used ...
PVD Film Method for Measuring the Temperature Distribution in Cutting Tools
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method to measure the temperature distribution in cutting tools is reported. In this method, a thin PVD (physically vapor deposited) film deposited on a cutting tool is used as a thermal ...
Friction Reducing Actions of Inclusions in Metal Cutting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The friction reducing actions of the inclusion grains in metal cutting were discussed experimentally and theoretically. At first, a model of the friction reducing action of a single inclusion ...
Theory of Frictional Vibration in Wet Clutches Considering Poroelastic Properties of Paper-Based Facing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new theory on frictional vibrations of paper-based friction material considering the interaction between its deformation and the consequent lubricant flow inside it. A ...
A Fast Method for Calculating Dynamic Coefficients of Finite Width Journal Bearings With Quasi Reynolds Boundary Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a fast method for calculating the dynamic coefficients of the finite width journal bearings under quasi Reynolds boundary condition in which the trailing boundary line is ...
An FFT-Based Method for Rough Surface Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastic contact between a rigid plane and a halfspace whose surface height is described by a bandwidth-limited Fourier series is considered. The surface normal displacements and contact pressures ...
