A Statistical Analysis in Solid Film Lubrication
(The American Society of Mechanical Engineers (ASME), 1963)A factorial experiment was designed for evaluating the performance of a ceramic bonded solid film lubricant consisting of PbS/B2 O3 in a 6:1 weight ratio. The effects of three factors, each ... -
Correlation of the Coefficient of Adhesion With Various Physical and Mechanical Properties of Metals
(The American Society of Mechanical Engineers (ASME), 1963)The coefficients of adhesion determined by a modification of the twist-compression bonding method are compared with the following properties of metals: crystal structure, hardness, surface energy, ... -
Analysis of a Rolling-Element Idler Gear Bearing Having a Deformable Outer-Race Structure
(The American Society of Mechanical Engineers (ASME), 1963)Conventional calculations of ball and roller bearing carrying capacity and fatigue life assume that the raceway bodies are rigid structures and that all elastic deformation occurs at the rolling ... -

Effects of Two-Dimensional, Sinusoidal Roughness on the Load Support Characteristics of a Lubricant Film
(The American Society of Mechanical Engineers (ASME), 1963)An analytical study is made of the effects of two-dimensional, sinusoidal roughness on pressure and shear stress in a lubricant film between two parallel plates engaged in steady, parallel, ... -
Static and Dynamic Properties of Partial Journal Bearings
(The American Society of Mechanical Engineers (ASME), 1963)The liquid lubricated partial journal bearing is analyzed in an approximate yet accurate manner in order to obtain its static and dynamic properties. The solution of the governing differential ... -
Squeeze Films for Rectangular Plates
(The American Society of Mechanical Engineers (ASME), 1963)A theoretical analysis is made of the normal approach of flat and curved rectangular plates which are separated by a thin film of lubricant. Load capacity curves are presented and some typical ... -
The Frequency Responses and Jump-Resonance Phenomena of Nonlinear Feedback Control Systems
(The American Society of Mechanical Engineers (ASME), 1963)A method is presented for analyzing the frequency responses and jump-resonance phenomena of nonlinear feedback control systems of any order. The nonlinearities treated in this paper are those ... -
A Simple Iterative Procedure for the Identification of the Unknown Parameters of a Linear Time Varying Discrete System
(The American Society of Mechanical Engineers (ASME), 1963)A new “steepest descent” approach to the “adaptive control system” problem of the determination of the process dynamics of a time varying system is analyzed in considerable detail. The unknown ... -
