Development of a General Procedure to Formulate Four Pole Parameters by Modal Expansion and Its Application to Three-Dimensional Cavities
(The American Society of Mechanical Engineers (ASME), 1990)If an acoustic system has one or more large dimensions compared to the shortest wave length of interest, the pressure responses which are necessary to formulate four pole parameters have to ... -
Pseudo-High-Speed Balancing
(The American Society of Mechanical Engineers (ASME), 1990)In industries like the aircraft gas turbine, trans-critical or super-critical operating speeds are quite common, and rotating machinery must be mass produced with very demanding precision in ... -
The Effect of Transverse Shear Deformation on the Natural Frequencies of Layered Composite Paraboloidal Shells
(The American Society of Mechanical Engineers (ASME), 1990)An analysis is presented for the study of the effect of transverse shear deformation on the natural frequencies of layered composite paraboloidal shells. The applicability of linear shell theory ... -

Analytical and Experimental Study of the Vibration of Bonded Beams With a Lap Joint
(The American Society of Mechanical Engineers (ASME), 1990)A theoretical model to study the flexural vibration of a bonded lap joint system is described in this paper. First, equations of motion at the joint region are derived using a differential ... -
Power Flow Finite Element Analysis of Dynamic Systems: Basic Theory and Application to Beams
(The American Society of Mechanical Engineers (ASME), 1989)A power flow analysis has been developed for predicting the vibration response of dynamic systems to high frequencies at which the traditional finite element method is no longer practical. As ... -
Faster Calculations of Sound Radiation from Vibrating Cylinders Using Variational Formulations
(The American Society of Mechanical Engineers (ASME), 1989)Prediction of the sound radiation from a vibrating body often requires a computation of the acoustic pressure on the body’s surface, given the normal surface vibration. This paper explores what ... -

The Development of Natural Modes of Free Vibration for Linear Discrete Systems from the Synchronous Motion Assumption
(The American Society of Mechanical Engineers (ASME), 1989)By using the method of separation of variables, or more precisely, the method of searching for synchronous motions, conditions are derived under which a linear discrete viscously damped system ... -
A Vibration Diagnosis Approach to Structural Fault
(The American Society of Mechanical Engineers (ASME), 1989)In this paper the sensitivity of structural vibration parameters to fault is analyzed. The frequency response function, which is sensitive to structural fault and able to reflect structural ... -
Active Control of Impact Vibration Using Feedforward Control Method
(The American Society of Mechanical Engineers (ASME), 1989)For the purpose of developing a vibrationless forge hammer, this paper presents a principle of the vibrationless forge method based upon an active vibration control technique. Then, from a ... -
Modeling and Vibration Analysis of Friction Joints
(The American Society of Mechanical Engineers (ASME), 1989)This paper presents a microslip model of friction joints, which may be viewed as a generalization of the simple model considered by Menq et al. (1986a). Laboratory experiments have shown that ... -
Analysis of a High-Speed Flexible Four-Bar Linkage: Part II—Analytical and Experimental Results on the Apollo

Passive Diagnostics and Reliability Experiment: Application in Machine Condition Monitoring
(The American Society of Mechanical Engineers (ASME), 1989)For many critical machines the only source of diagnostic knowledge is passive experiment during machine operation. If we treat the observed vibration symptoms for a group of machines as an ... -
A Design Criterion for Avoiding Resonance in Lumped Mass Normal Mode Systems
(The American Society of Mechanical Engineers (ASME), 1989)A simple design criterion that determines whether a normal mode multiple degree of freedom damped linear lumped parameter system can or cannot resonate is presented. The relations are derived ... -
On the Hybrid Vibration Isolation Method
(The American Society of Mechanical Engineers (ASME), 1989)For the purpose of isolating the vibration transmission from machines to soil and vice versa, this paper presents a new active vibration isolation method, that is, a hybrid vibration isolation ... -
Improvement of a Reduced Torsional Model by Means of Parameter Identification
(The American Society of Mechanical Engineers (ASME), 1989)Turbogenerator sets in operation may be excited to transient torsional vibrations by dynamic electrical moments at the generator due to short-circuits or faulty synchronization. For the solution ...
