Comparison of the impact test and the harmonic test in measurements of natural resonant frequencies of circular saw blades
Abstract
In this paper results of measurements of natural resonant frequencies of circular saw blades with the impact test and the harmonic test are presented. Comparison of these two methods revealed that during testing of circular saw blades, in which bodies the open and closed notches (cuts) for cleaning of knives are present, with the harmonic test method it has been observed appearing of quasi-twin resonant frequencies, whereas the impact test method could not allow to recognize them , because it does not clearly confirm the occurrence of such frequencies.
