Abstract

condition of rotary equipment without involvement of experts. However, informative features of defects in the frequency domain strongly depend on the rotational speed of the equipment shafts, which can lead to incorrect operation of diagnostic systems. To improve the stability and accuracy of automatic vibration-based diagnostics in the frequency domain, algorithms for refinement of the shaft rotational speed without using additional devices are proposed.
