Aircraft structures are prone to vibrations due to their lightweight construction. In most cases, these vibrations are not critical. They decay due to damping effects from aerodynamic forces and ...

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 ...

In vibration-critical applications, understanding how a PCB deforms under excitation is essential. Using massively parallel ...

Jet engine vibration is arguably the worst enemy of a typical aircraft maintenance team. Parts which are out of balance can eventually result in a cracked turbine, fan, and compressor components, as ...

Part 1 of this series addressed the advantages and disadvantages of various vibration sensors; Part 2 examined signal conditioning and system hardware selection and configuration. I’ll wrap up by ...

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 ...
