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 ...

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 ...

Abstract: In order to solve the problem of vibration safety of new energy vehicle power battery pack, this paper takes a certain blade battery pack as the research object and carries out random ...

In high-stakes defense and industrial environments, mechanical failures in rotating machinery (e.g., helicopter transmissions, tank track systems) can lead to mission abortion or safety hazards. The ...

Laser doppler vibrometry enables simultaneous measurement at dozens of points across populated PCBs, revealing component-level failure risks that accelerometers miss. Printed circuit boards (PCBs) ...
