TOPIC: Resonance - A Sleeping Giant Resonance is never an easy problem to deal with-in particular, structural resonance. It’s like a sleeping giant that you never want to awaken. PRESENTERS: Glen Powell - Hydro Reliability Services - Reliability Engineer Ralph Fergusson - Hydro Scotford - Account Manager DESCRIPTION: Resonance is a condition that is often misdiagnosed and commonly goes undiagnosed, resulting in persistent high amplitude vibration issues for long periods. Resonant excitation occurs when a forcing function (generated by rotating equipment) coincides with a structural natural frequency. This problematic occurrence typically results in highly directional vibration and increased amplitudes that can be difficult to resolve without the proper engineering approach. Resolving structural resonance problems can be quite expensive when trial and error methods are attempted in the field (such as attempting to stiffen or detune a structure). This webinar will focus on ways to identify structural resonance and how to eliminate the high vibration amplitudes that commonly accompany it without the guesswork.
