Vibration testing and analysis. This has been referred to in a number of different ways, most of which are not meant to be complimentary. Voodoo box, black magic, rocket scientist stuff, etc. It is an ...

Rotor dynamics and vibration analysis encompass the study of the behaviour of rotating machinery subjected to various excitations and uncertainties. This field, which lies at the intersection of ...

Discover how PBS eXpress is transforming engine vibration analysis with advanced features designed for efficiency and precision in turbine maintenance. The PBS eXpress system was heavily influenced by ...

Many readers probably think “black magic” describes the math involved in finding the dynamic response of a structure from random excitation. When can you be sure you have jumped through all the ...

Vibration analysis is a powerful and non-invasive way to measure, understand, and quantify the internal dynamics of mechanical systems, but the cost of the necessary instrumentation is sometimes a ...

What is modal analysis? Evaluating vibration sensor enclosures and their natural frequencies. Determining the most important modes and frequencies with the mode participation factor. A close look at ...

High vibration is a common problem for motors installed on top of vertical pumps. Its source can stem from a mechanical issue with the pump, motor, or coupling — or even hydraulic forces from the pump ...

Researchers at University of Tsukuba have developed a noncontact vibration measurement method using an event camera, a sensing technology inspired by biological vision. By applying geometric analysis ...

NOTE: Click on images or equations to make them larger. Last month’s column discussed the basics of simulating resonant or natural vibration frequencies as an introduction to performing advanced ...
