Abstract
Surface grinding machines are mainly used to reduce the surface roughness of workpieces and to obtain accurate dimensions, that is, to perform finishing operations of technological processing processes. It should be noted that the general layout of the oscillatory system of surface grinding machines, the geometric dimensions of the grinding wheels, workpieces and the methods of their fastening have significant differences from other types of grinding machines. This circumstance determines the need to substantiate the models of vibroacoustic dynamics of those elements of the general oscillatory system of the objects of study, the intensity of sound radiation of which leads to an excess of sound pressure levels at the workplaces of machine operators over the maximum permissible values. The acoustic models considered in the article allow theoretically calculating the spectral sound pressure levels of the above sources of noise discomfort at the stage of designing and installing equipment, as well as identifying frequency intervals and the values of excess over sanitary standards.
