Resonance
Resonance is a core engineering term. Definition, usage notes, and a practical example.
Definition
Resonance is vibration amplification when excitation frequency approaches natural frequency.
Why it matters
It increases fatigue risk in rotating equipment, frames, and joints.
How it is used
In a design check, first define the relevant load, dimension, material, or flow condition. Then interpret this term by its role in the formula and compare it with limits.
Example
If a fan suddenly vibrates at a certain speed, it may be near resonance.
