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 ...

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 ...
