Determination of parameters of concrete mixers and generalization of optimal solutions by the method of similar transformations

Abstract

Introduction. Increasing of the efficiency of using of the construction machinery, in particular, concrete mixers, is an important task of construction production, affecting the reduction of construction costs and increasing the efficiency of machine use.

The aim is to show the possibilities of the considered method of physical large-scale modeling for determining the optimal parameters of machines under given operating conditions.

Materials and methods. The optimal parameters of concrete mixers were determined by analyzing mathematical models of the working cycle duration of concrete mixers, the optimal solutions obtained were scaled to various operating conditions using the similarity theory discussed in the article.

Results. The article presents graphs obtained using the proposed methods, demonstrating the presence of optimal zones of efficient use of concrete mixers under certain operating conditions.

Conclusions. The considered provisions show that for concrete mixers, there are ratios between the main technical parameters m, N, q, T, l characterized by scale coefficients.
