eng.natural-frequency Calculator
Calculates the natural frequency and period of a spring-mass system from stiffness and mass. Natural frequency fn = (1/2π)√(k/m) — operating machinery above the natural frequency (supercritical) avoids resonance during startup by quickly passing through the critical speed.
Inputs
K
Reference formula or conversion factor shown for context.
M
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
C
Reference formula or conversion factor shown for context.
F Exc
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Results
natural frequency (Hz)
Frequency at which the structure resonates freely (Hz). If machinery operates near this, resonance can amplify vibrations dangerously. Engineers detune structures to avoid it.
damping ratio ζ
The proportional relationship between two quantities.
damped frequency (Hz)
Sample size or count used in the calculation.
transmissibility ratio
The proportional relationship between two quantities.
system type
The classification or type assigned based on the inputs.
resonance risk
Overall risk level based on the computed score or classification. Higher risk may call for mitigating actions or additional review.
