An Application of Diakoptics in the Determination of Turbine Bucket Frequencies by the Use of Perturbations
(The American Society of Mechanical Engineers (ASME), 1969)The method of Diakoptics, originally designed for the computation of linear electrical network, is also applicable to those linear systems of mechanics, where major subsystems are not too strongly ... -
The Dynamic Stability of Rotor/Stator Radial Rubs in Rotating Machinery
(The American Society of Mechanical Engineers (ASME), 1969)The classic phenomenon of “dry friction whip,” generally associated with unlubricated journal bearings, is here reconsidered as playing an important role in the dynamic stability, and consequent ... -
Bending-Bending Mode of a Rotating Tapered-Twisted Turbomachine Blade Including Rotatory Inertia and Shear Deformation
(The American Society of Mechanical Engineers (ASME), 1969)This paper presents the effect on natural frequency and mode shape of the inclusion of terms that are present in the general equations of motion to describe phenomena associated with Rotatory ... -
Transfer Functions for Helical Springs
(The American Society of Mechanical Engineers (ASME), 1969)This study reports the results of an analytical and experimental investigation of helical springs subjected to vibratory motion. Transfer functions are presented for both displacement and transmitted ... -
A New Criterion for Optimizing Linear Vibration Isolator Systems Subject to Random Input
(The American Society of Mechanical Engineers (ASME), 1969)A new performance criterion is proposed for the synthesis of optimum linear isolators subject to random inputs. This criterion is based upon the values of displacement and acceleration; the ... -
Nonlinear Vibrations of a Beam With Pinned Ends
(The American Society of Mechanical Engineers (ASME), 1969)This paper describes theoretical and experimental investigations of the large-amplitude vibrations of a flexible beam simply supported on a nearly rigid base. The beam is designed to minimize ... -
Response of Linear Systems to Magnitude Limited Random Excitation
(The American Society of Mechanical Engineers (ASME), 1969)In many situations, encountered both in the field and in the laboratory, the excitation produced by a broadband random source has many of the characteristics of a signal having a Gaussian ... -
Theoretical and Experimental Investigation of Electrohydraulic Vibration Isolation Systems
(The American Society of Mechanical Engineers (ASME), 1969)This paper presents the results of an investigation of electrohydraulic vibration isolation systems that employ multiple electronic feedback signals to control the action of a hydraulic actuator ... -
The Influence of Dissipative Heating on the Loss Factor of a Viscoelastically Damped Beam
(The American Society of Mechanical Engineers (ASME), 1969)The influence of dissipative heating on the loss factor of a beam with a constrained viscoelastic layer is examined analytically and experimentally for the case in which the extensional stiffness ... -
Expected Equivalent Damping Under Random Excitation
(The American Society of Mechanical Engineers (ASME), 1969)An analytical technique for obtaining an expected equivalent damping coefficient for a single-degree-of-freedom structure under random loading is discussed and illustrated. The expected energy ... -
Limit Cycles and Stability of a Nonlinear Two-Degree-of-Freedom Autonomous Vibratory System
(The American Society of Mechanical Engineers (ASME), 1969)A perturbation technique based on small reciprocal of rotational inertia is used to find limit cycles for a system consisting of a spring, dashpot, and mass upon which is mounted an eccentric ... -
An Explanation of Low-Speed Chatter Effects
(The American Society of Mechanical Engineers (ASME), 1969)At low machining speeds, self-excited chatter behavior is dominated by factors which have never been satisfactorily explained. By studying the forces acting on the cutting tool right behind the ... -
Vibration of Containing Structures by Sound in the Contained Fluid
(The American Society of Mechanical Engineers (ASME), 1969)A system which consists of a rigid rectangular box with one simply supported flexible wall is analyzed by numerical and statistical methods for the internal acoustostructural mode coupling factors ... -
Periodic Motions of a Two-Body System Subjected to Repetitive Impact
(The American Society of Mechanical Engineers (ASME), 1969)The dynamics of a widely used class of hammer impact machines are investigated on the basis of a two-degree-of-freedom idealization. The difficulty in the problem is due to the repetitive ... -
