Abstract
Comparison of natural frequencies of a circular saw blade obtained empirically and with FEM. The knowledge of the natural frequencies’ values of circular saw blades is necessary to determine the minimal critical rotational speed in which they can work with required stability. Moreover, testing the circular saw blades with more complicated shapes, e.g. which have additional holes inside blades for cleaning knifes or additional indirect teeth in gullets, reveals some kind of problematic properties of these saw blades. The aim of this paper is to compare results from two kinds of methods, which have been used for determining of the resonant frequencies of the circular saw blades. The harmonic test and the FEM were applied.
