INVESTIGATION OF NOISE AND VIBRATION OF CUTTING CIRCULAR SAWS
DescriptionThe article presents the results of theoretical studies of noise cutting circular sawing machines. Practical calculation of the noise spectra is based on the determination of the dependency of the sound pressure of the noise sources of the object of study. In the sound system, circular sawing machines sound energy is emitted by the following sources: disc cutter and the mandrel. Therefore, the dominant noise sources should be allocated to the technological subsystem "tool – mandrel” with a bit less rigidity than the carrier system of the machine and directly receives the cutting forces when milling. Thus, it is possible to reduce sound pressure levels in almost two ways: by increasing absorption production facilities and (or) decrease in sound pressure of the noise source. In this work, we have justified the second way – reduction of the intensity of acoustic radiation of the source
