The article deals with analysis of possible applications easing by Short Time Fourier transformation, in determining the natural frequencies and damage to the monitored equipment. We have focused on the problem when the maximum speed of the equipment at start-up is limited due to the excitation of resonances around this maximum speed. If we are concerned about the frequency region near resonance and above this, and when we do not want to risk damage to the equipment when passing through resonance, then the solution can be complicated. Our solution is based on the use of the excitatory properties of harmonic frequencies generated by the system to build a facility in the desired frequency range. The procedure was applied to solve reducing vibration of the structure in the steel mills and the extension of the interval of possible use of frequencies in production.
