Comparative analysis of mathematical models for the screw unit in small continuous-operation plastering machines

Вірченко, В.В.

The development of modern construction necessitates improving mechanized mortar application methods. One of the key elements of small-sized continuous plastering units is the screw as-sembly, which ensures uniform supply and mortars transportation. Its effectiveness directly depends on the design parameters, physical and mechanical properties of the material and operating conditions. To analyze the operation of the screw assembly, various mathe-matical models are used to describe hydrodynamic processes, mechanical interactions between system components and mortar flows characteristics. Important criteria for choosing mathematical models are forecasting accuracy, implementation complexity, and practical application. The article provides a detailed review of existing modeling ap-proaches and identifies their features. In the course of the study, a mathematical model’s comparative analysis used to describe the screw operation assembly was carried out. Their advantages and disadvantages, as well as areas of application, are established. It is shown that each of the models has its own applicability limits and forecasting accuracy de-pending on the type of working environment and unit design features. Recommendations for choosing the most effective mathematical model for predicting the screw assembly operation of small-sized plastering units are proposed. The results obtained contribute to improving the efficiency of plastering units through a well-founded choice of mathematical models for analyzing their work processes. The defined evaluation criteria can be used to further improve theoretical approaches to calculating the characteristics of the screw assembly and its optimization.
