Vibration Testing an overview , ScienceDirect Topics

Modal testing in single mode vibration using the impulse-frequency response method (Suarez et al., 1984; Gibson, 1994, 2000 Gibson, 1994 Gibson, 2000) can be used to measure the flexural modal frequencies and modal loss factors of specimens. In this method, impulsive excitation is applied using an electromagnetic hammer and the transverse displacements of the beam are measured with respect to

EXPERIMENTAL MODAL ANALYSIS maintenance

Experimental modal analysis has grown steadily in popu-larity since the advent of the digital FFT spectrum analyzer in the early 1970’s. Today, impact testing (or bump testing) has become widespread as a fast and economical means of finding the modes of vibration of a machine or structure. In this paper, we review all of the main topics associated with experimental modal analysis (or modal

Effect of Thickness of Damping Material on Vibration

Viscoelastic material among the damping materials is widely used to dissipate the structural vibration energy. Three-layer sandwich beams, made of two elastic outer layers and a viscoelastic layer sandwiched between them, are considered as damping structural elements. This paper presents the effect of thickness of constrained damping material on modal loss factor of vibrating structures

Modal Experiment Research on Fluid-Solid Coupling

Abstract: A vibration wave generated actively by hydraulic vibration exciter was studied, and an experimental system based on the theory of water hammer was designed. The new developed vibration exciter is driven by the motor whose rotary speed can be adjusted by frequency converter, by means of which transient pulsating flow is generated regularly. Consequently the piston of hydraulic

be tested using a modal hammer. The modal hammer will strike the positioner with a measurable force and duration that will excite the natural frequencies of the system. Using an array of accelerometers, the vibration amplitudes will be recorded. Using the data, a transfer function between input force and vibration response can be calculated to characterize the system response. A Fourier
