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 ...

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 ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

A key goal in several structural dynamics studies is to define the locations on a structure where failures are most likely to occur. Fatigue damage is a result of fluctuating strain. Therefore, it is ...

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 ...

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 ...

A way of monitoring household appliances by using machine learning to analyse vibrations on a wall or ceiling has been developed by researchers in the US. Their system could be used to create ...
