Machinery Noise May Indicate Loss of Efficiency and Severity of Dynamic Stresses
(The American Society of Mechanical Engineers (ASME), 1971)The general consensus about industrial noise is that it may have harmful effects on hearing, is at best a nuisance, and therefore should be absorbed or alleviated. Although not as universally ... -
Design and Performance of High-Pressure Blowoff Silencers
(The American Society of Mechanical Engineers (ASME), 1971)Through the application of fluid dynamic and acoustic theory, the noise generation of a high pressure blowoff can be approximated. The effects of silencer configurations can likewise be predicted ... -
A Study of the Stresses Around Elliptical Holes in Flat Plates
(The American Society of Mechanical Engineers (ASME), 1971)The theoretical elastic stress distribution is presented for a thin flat plate of finite width which contains an elliptical hole. Various uniaxial and biaxial in-plane loads are applied to the ... -
Reduction of Alternating Stress Range Around Holes in Flat Plates by Use of Inserts
(The American Society of Mechanical Engineers (ASME), 1971)Airy stress functions are established herein for the solution of hollow annular interfering inserts in thin flat plates which extend to infinity. The equations presented are solved for the case ... -
Spiral Power Springs. Part 2—Design
(The American Society of Mechanical Engineers (ASME), 1971)The theoretical model developed in a preceding companion paper for predicting the torque-turn behavior of a spiral power spring is extended in an effort to improve the practical applicability. ... -
Spiral Power Springs. Part 1—Theory
(The American Society of Mechanical Engineers (ASME), 1971)This paper is the first of a series of two dealing with spiral power springs (i.e., motor springs or clock springs). A new theoretical treatment is presented which, neglecting friction, predicts ... -
Optimum Design of Prismatic Bars Subjected to Longitudinal Impact
(The American Society of Mechanical Engineers (ASME), 1971)This paper presents a procedure for the automated selection of the configuration of stepped prismatic bars placed between given hammers and anvils to produce maximum force amplification or ... -
Analysis and Design of Multistage Torsion Springs
(The American Society of Mechanical Engineers (ASME), 1971)An experimental and theoretical study of a “multi-stage torsion spring” is presented. The spring is designed for high torsion (25 kg-m), considerable angular displacement (±20 deg), space ... -
The Damping Effects of Viscoelastic Materials: Part 2—Transverse Vibrations of Plates With Viscoelastic Coatings
(The American Society of Mechanical Engineers (ASME), 1971)An energy method is employed to analyze a nonhomogeneous, damped plate composed of an elastic (metal) layer and an unconstrained viscoelastic layer. This analysis is limited to the case of ... -
The Damping Effects of Viscoelastic Materials: Part 1—Transverse Vibrations of Beams With Viscoelastic Coatings
(The American Society of Mechanical Engineers (ASME), 1971)An energy method similar to Rayleigh’s method is employed to analyze a nonhomogeneous, damped beam composed of an elastic (metal) layer and an unconstrained viscoelastic layer. This analysis is ... -
Vibrations of Elastic Connecting Rod of a High-Speed Slider-Crank Mechanism
(The American Society of Mechanical Engineers (ASME), 1971)The research involved in this paper falls into the area of analytical vibrations applied to planar mechanical linkages. Specifically, a study of the vibrations, associated with an elastic ... -
Vibration Isolation With Nonlinear Damping
(The American Society of Mechanical Engineers (ASME), 1971)This paper discusses the performance characteristics of single degree-of-freedom vibration isolation systems in which the isolator damping force is proportional to the relative velocity across the ... -
Complete Force Balancing of Spatial Linkages
(The American Society of Mechanical Engineers (ASME), 1971)A new method permits the complete force balancing of spatial linkages such as the RSSR and RSSP mechanisms. Operator equations are written describing the location of the center of mass for ... -
A System of Specification of Lathe Tool Nomenclature
(The American Society of Mechanical Engineers (ASME), 1971)From the mechanics of turning operation, a system of specification of lathe tool nomenclature is derived. The system also satisfies the criteria of ease of grinding and ease of inspection. -
Grinding Wheel Elasticity
(The American Society of Mechanical Engineers (ASME), 1971)The deflection of individual abrasive grains in the cutting surface of a vitrified grinding wheel has been postulated to explain many fine grinding results; however, the magnitude of the ... -
