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 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 ...

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 ...

Polytec's PSV-400-3-dimensional scanning vibrometer measures vibration characteristics of aerospace structures, such as aging aircraft, components or preproduction products. Three independent sensor ...

From left, J.D. Rice, Trevor Michelson and Chris Seck look at a monitor in Seck’s lab. The three are wearing safety glasses to protect against the laser beams used by the scanning vibrometer, which is ...

Rolling tires stimulate a considerable amount of passenger car noise (NVH) inside and outside the passenger cabin for a large range of driving conditions. These are three important reasons this ...

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 ...
