Natural Frequency. The equation for the natural frequency of vibration is: Where; f n = undamped natural frequency (Hz) k = spring stiffness (N/m) m = mass (kg) Note! This equation will not work in mm! This shows that in order to raise the natural frequency, we can either increase the stiffness or reduce the mass.
