Regression models of technological processes post-harvesting grain

Abstract

The paper presents the regressive models of technological processes of post-harvest grain processing (PHGP). In the technological model of the functioning of the EMP system, there are interrelated indicators of the quality of equipment operation with the probability of being at acceptable levels of operating conditions, the technological state of the system and internal obstacles. Presented is a technological model of the PHGP system and regressive models of the functioning of grain cleaning machines in the form of one and three subsystems. The developed technological model of the functioning of the technical equipment of the PHGP shows the need to determine the technological tolerances of the performance indicators of the grain cleaning machine in the conditions of their normal functioning, should be taken into account when developing methods for calculating the parameters of the technical equipment process of the PHGP. Regressive models of technological processes of the PHGP in a normalized form is the basis for obtaining mathematical models for predicting the quality indicators of the functioning of machines and units in field conditions and for carrying out a machine experiment by the method of simulation.
