To determine the minimal critical rotational speeds of the circular saw blades is the fundamental aspect of obtaining the range of the rotational operating speeds, by which the circular saw blade can work with required stability. While for the circular saw blades with full-homogeneous bodies the determination of such rotational speeds is the relatively low level of difficulty function, whereas for circular saw blades with more complex shapes (with any kinds of holes in the body, e.g. holes for cleaning knives, thermal stress compensators, indirect teeth etc.) that task becomes much more complicated. The aim of this paper is to compare the results of the minimal critical rotational speeds’ determination of the circular saw blades, which feature is the appearance the phenomenon of quasi-twin resonant frequencies, which results were obtained by the experimental method and with the FEM modeling.
