Our Training

Wayne Tustin

I’m blessed with good health and a supportive family, and greatly enjoy my business and professional activities. Helping adults learn (about vibration and shock measurement and testing, in my case) is fun. May I help you (or someone you know) to learn about these subjects? We’ll both enjoy the experience.

Our Resources

We’re watching an electronic card that is being multiaxis randomly (all frequencies simultaneously) vibrated. It’s receiving much the same input as if it were aboard a powered-flight rocket or other vehicle. You can see the various parts of this assembly moving relative to other parts. Failure is likely. We’d rather have failure occur here, in the lab, than in service.

ERI greatly appreciates Qualmark sharing this video. Excitation here was from numerous Qualmark pneumatic hammers. Similar responses are seen when such hardware is excited by multiple electrohydraulic (EH) or electrodynamic (ED) shakers.
