Title: Note: A kinematic shaker system for high amplitude, low frequency vibration testing

Abstract

This note describes a shaker system capable of high peak-velocity, large amplitude, low frequency, near-sinusoidal excitation that has been constructed and employed in experiments on the inhibition of Rayleigh-Bénard convection using acceleration modulation. The production of high peak-velocity vibration is of interest in parametric excitation problems of this type and reaches beyond the capabilities of standard electromagnetic shakers. The shaker system described employs a kinematic linkage to two counter-rotating flywheels, driven by a variable-speed electrical motor, producing peak-to-peak displacements of 15.24 cm to a platform mounted on two guide rails. In operation, this shaker has been demonstrated to produce peak speeds of up to 3.7 m/s without failure.

Dynamic stabilization of the Rayleigh-Bénard instability by acceleration modulation

Journal Article Swaminathan, Anand ; Garrett, Steven L. ; Poese, Matthew E. ; ... - Journal of the Acoustical Society of America

This paper presents the results of an experimental investigation of the parametric stabilization of Rayleigh-Bénard convection through the imposition of sinusoidal vibration. The ability to dynamically stabilize Rayleigh-Bénard convection using acceleration modulation is of interest to groups who design and study thermoacoustic machines as the introduction of parasitic convection can have deleterious effects on the desired operation and thermodynamic efficiency of the device. These performance issues caused by suspected convective instability have been seen both in traveling wave thermoacoustic refrigerators and cryogenic pulse tube chillers.

Piezoelectric Shaker Development for High Frequency Calibration of Accelerometers

Journal Article Payne, Bev ; Harper, Kari K ; Vogl, Gregory W - AIP Conference Proceedings

Calibration of vibration transducers requires sinusoidal motion over a wide frequency range with low distortion and low cross-axial motion. Piezoelectric shakers are well suited to generate such motion and are suitable for use with laser interferometric methods at frequencies of 3 kHz and above. An advantage of piezoelectric shakers is the higher achievable accelerations and displacement amplitudes as compared to electro-dynamic (ED) shakers. Typical commercial ED calibration shakers produce maximum accelerations from 100 m/s{sup 2} to 500 m/s{sup 2}. Very large ED shakers may produce somewhat higher accelerations but require large amplifiers and expensive cooling systems to dissipate heat. Duemore »« less

KINEMATIC AND DYNAMIC ANALYSIS OF RADIAL ARM INDEXING MECHANISM. TOP TRANSFER MACHINE

Technical Report Nicoll, D ; Timin, M E

Results of analysis of the top transfer machine used in fuel handling are presented. Results indicate that the mechanism will satisfactorily adjust the radial position of the head within the limits set by the self-centering head. By jogging the electrical control buttons and holding the duration of contact down to 1/10 sec, the machine will be positioned within 0.028 in. The horizontal speed of the pickup head, if the motor is maintained at synchronous speed, is 5.6 fps at the center position and 0.0105 fps at a position 59 in. from the center. However, the motor will not be maintainedmore »« less
Shaker-structure interaction modeling and analysis for nonlinear force appropriation testing

Journal Article Pacini, Benjamin R. ; Kuether, Robert J. ; Roettgen, Daniel R. - Mechanical Systems and Signal Processing

Nonlinear force appropriation is an extension of its linear counterpart where sinusoidal excitation is applied to a structure with a modal shaker and phase quadrature is achieved between the excitation and response. While a standard practice in modal testing, modal shaker excitation has the potential to alter the dynamics of the structure under test. Previous studies have been conducted to address several concerns, but this work specifically focuses on a shaker-structure interaction phenomenon which arises during the force appropriation testing of a nonlinear structure. Under pure-tone sinusoidal forcing, a nonlinear structure may respond not only at the fundamental harmonic butmore »« less

The Interstate-40 bridge shaker project

Technical Report Mayes, R L ; Nusser, M A

New Mexico State University organized an effort to perform static and dynamic damage-detection tests on the Interstate-40 bridge over the Rio Grande at Albuquerque. The opportunity was available because the 425-ft-long bridge was soon to be replaced. Sandia National Laboratories was asked to provide and operate a shaker that could exert 1000-lb peak amplitude forces for both sinusoidal and random excitations between 2 and 20 Hz. Two Sandia departments collaborated to design and build the shaker, using existing major components connected with Sandia-designed and -fabricated hardware. The shaker was installed and operated successfully for a series of five modal andmore » sinusoidal response tests.« less
