Regression analysis of the influence of auger surface hardness on its wear during dehydration of solid waste in a garbage truck

Abstract

The article is devoted to the study of the influence of the surface hardness of the auger on its wear during dehydration of solid waste in the garbage truck. Using the method of regression analysis, the logarithmic dependences of the screw wear depending on the hardness of its surface for different values ​​of the friction path are determined. Graphical dependences of augur wear depending on the hardness of its surface for different values ​​of the friction path are created, which confirms sufficient convergence of the obtained dependences. The additional regression analysis allowed to obtain the dependence of screw wear depending on the hardness of its surface and the friction path, which showed that during two weeks of operation and wear of the screw during dehydration of solid waste in the garbage truck increases the screw surface hardness 2310 MPa to 10050 MPa. dehydration of solid waste 16.7% to 1.5%, and hence reduce the cost of the process of dehydration in the garbage truck. The graphical dependence of the reduction of energy consumption of dehydration of solid household waste due to the increase of the hardness of the auger surface during its two-week wear is given. The expediency of further research to determine the rational material of the auger and ways to increase its wear resistance. The graphical dependence of the reduction of energy consumption of dehydration of solid household waste due to the increase in the hardness of the auger surface during its two-week wear is given. The expediency of further research to determine the rational material of the auger and ways to increase its wear resistance.
