Resonant Frequency
Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Resonant frequency is the natural frequency at which a system vibrates with maximum amplitude when excited. In mechanical systems, operating near this frequency can cause large oscillations and potential structural failure.
Example in context
“The pump motor was operating at 3600 RPM, close to the structural resonant frequency of the baseplate, causing excessive vibration.”
“Pompa motoru, taban plakasının yapısal rezonans frekansına yakın olan 3600 RPM'de çalışıyor ve aşırı titreşime neden oluyordu.”
Where engineers use it
Identifying resonant frequencies is critical in modal analysis to avoid operation near these speeds. Engineers perform impact testing or run-up tests to map frequencies and modify stiffness or mass to shift them.
Synonyms: natural frequency, eigenfrequency
Practice: can you use “Resonant Frequency” at work?
During a startup test, a centrifugal compressor shows a vibration spike at 2400 rpm. Estimate if this is the resonant frequency of the rotor or the foundation.

“We should avoid running the fan at its resonant frequency.”

Frequently asked questions
What does Resonant Frequency mean in engineering?
Resonant frequency is the natural frequency at which a system vibrates with maximum amplitude when excited. In mechanical systems, operating near this frequency can cause large oscillations and potential structural failure. In Mechanical Engineering, the term carries a usage-frequency rating of 10/10 in the Engineering English library.
How do you pronounce Resonant Frequency?
Resonant Frequency is pronounced /ˈrɛzənənt ˈfrikwənsi/ (IPA). The Engineering English app plays audio for the term and checks your pronunciation with speech recognition.
