Abstract:

The applications of high performance materials in the aerospace and in the automotive technology in the next years need to develop new vibration study, nondestructive testing, predictive maintenance and industrial control methods.The Laser Scanning Vibrometry and Holographic Interferometry methods of vibration study and nondestructive testing by modal analysis are described. The Laser Scanning Vibrometer PSV 400 is made by Polytec GmbH and the PSV software reconstructs the 3D model of the measured micro-deformation of the object.

Abstract:

A laser Doppler vibrometer was created with the ability to measure the vibrations of distant objects up to 250 meters away. The vibrometer is provided with a scanning system for automatic vibration measurement in an array of points. The control program moves the probe beam according to the research protocol, processes and store information. To demonstrate the capabilities of the system, we studied of the amplitude distribution of vibrations and the distribution of longitudinal stresses in a cantilevered tube located at a distance of 22 meters. The measurements at different frequencies are in g

In preparation for the challenges presented by future spacecraft systems, we explore state-of-the-art testing technologies and compare the results to demonstrated, proven methods. A non-contact Polytec PSV-400 scanning laser vibrometer (SLV) is used to characterize the frequency response of a 2 meter reflector in a typical modal test configuration. Complementary measurements are made simultaneously using a conventional accelerometer-based system, and the results are compared to determine the effectiveness of the non-contact tool.

This paper presents the validation of an experimental technique that maps the transfer of energy in vibrating structures. The technique is known as Experimental Spatial Power Flow (ESPF) and is unique in that it provides a spatially continuous representation of the power flow based on measurements from a scanning laser Doppler vibrometer. In this paper, the ESPF technique is validated by showing that ESPF results compare to within 10 percent of the results obtained using single point impedance head measurements.

Abstract:

Because a Scanning Laser Vibrometer (SLV) can perform vibration measurements with a high spatial resolution, it is an ideal instrument to accurately locate damage in a structure. Unfortunately, the use of linear damage detection features, as for instance FRFs or modal parameters, does not always lead to a successful identification of the damage location. Measurement noise and nonlinear distortions can make the damage detection procedure difficult. In this article, a combined linear-nonlinear strategy to detect and locate damage in a structure with the aid of a SLV, will be proposed. To minimiz

When spatially dense mobility shapes are measured with scanning laser Doppler vibrometers, it is often impractical to use phase-separation modal parameter estimation methods due to the excessive number of highly coupled modes and to the prohibitive computational cost of processing huge amounts of data.

The vibration-based damage identification method extracts the damage location and severity information from the change of modal properties, such as natural frequency and mode shape. Its performance and accuracy depends on the measurement precision. Laser Doppler vibrometer (LDV) provides a noncontact vibration measurement of high quality, but usually it can only do sampling on a single point. Scanning LDV is normally used to obtain the mode shape with a longer scanning time. In this paper, a damage detection technique is proposed using a self-synchronizing multipoint LDV.

Asphalt mixtures are the most common types of pavement material used in the world.

One of the important properties of asphalt mixtures is the complex modulus of elasticity. This parameter can be determined using different standardized methods, which are often expensive, complex to perform, and sensitive to the experimental setup. Therefore, recently, there has been considerable interest in developing new, easier, and more comprehensive techniques to invest
