Mathematical and computer models of the gas flow movement near the shaped cover of the rough grinding machine

Abstract

Abstract The aim of the study is to improve working conditions for operators of grinding machines by ensuring sanitary standards for dustiness in the workplace. To achieve the goal, it is necessary: to develop a mathematical model for the dispersion of abrasive-cast iron dust when grinding fragile parts; mathematical and computer models of the aspiration of the rough grinding machine; to propose an engineering method for calculating the efficiency of a cover in the form of a built-in casing and the choice of elements of a dust removal and dust collection system for grinding machines of the class under discussion. The article presents the mathematical and computer models of aspiration of a roughing-grinding machine, implemented in modern software Ansys. The dependencies, describing the flows of velocity fields in the closed area of the grinding wheel are obtained, which influence the formation of flow lines near the shaped cover of the roughing-grinding machine, which will make it possible to determine the efficiency of the cover of the roughing-grinding machine, including the design stage in future.
