Abstract
The article considers roller table mechanisms widely used for feeding blanks of various configurations to the processing zone of various types of technological machines, in particular, such as forging and pressing equipment, metal-cutting and woodworking machine tools. This equipment creates increased levels of noise and vibration at the workplaces of pro duction personnel. The oscillating systems of roller tables for various technological machines have an identical layout and include: feed rolls, which are cylindrical elements, a supporting system, which is a welded structure made of channels. It was found that the differences actually consist in the geometric dimensions and the number of elements included in the common oscil lating system. Due to the identity of the oscillatory system, the modeling of vibroacoustic dy namics processes, on the basis of which the vibration levels of sound pressure and sound power are determined, is performed on the basis of a single methodological approach.
