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 ...

Random vibration testing provides energy simultaneously at all frequencies. Vibration testing can help ensure that your new design will survive its intended environment. The problem is knowing how ...

Highly Accelerated Lifecycle Testing (HALT) is the gold standard for physical testing of a product to determine reliability issues. Deriving the physical constraints and fatigue issues for a design ...

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 ...
