Laser vibrometers consist of a low-power laser beam, picking up the signature of a vibrating object and transferring it into an output proportional to velocity and displacement that the researcher can ...
The Air Force Institute of Technology (AFIT; Wright Patterson AFB, OH) will employ Polytec's PSV-400-3D scanning vibrometer for experimental modal analysis. AFIT will use the tool, which permits ...
During the ANSYS Conference & 28 th CADFEM User’s Meeting held 2010 in Aachen, Germany, a new approach was presented, which facilitates the integration of experimental modal analysis test into the CAE ...
The Polytec Inc. PSV-400-3D scanning laser vibrometer, utilized in experimental modal analysis, uses Doppler shift of back-scattered laser light to determine instantaneous velocity and displacement of ...
A hammer impact must be repeated for each scan point to measure points consecutively with a Polytec Scanning Laser Vibrometer. As a result, automated modal hammers such as the SAM, developed by ...
In biomechanics, non-contact laser Doppler vibrometry is a highly important and potent tool. In determining the dynamic properties of a pelvic bone, recent experiments have relied on deflection ...
