Abstract
Introduction. The paper describes the actual problem of increasing the operating life of the brush working body (BWB) and improving the cleaning quality. Moreover, the authors discuss the factors affecting the quality of the road surface cleaning and the brush pile resource.
Materials and methods. The research presents the results of the interaction process of the BWB pile with the cleaned surface of the roadway. In addition, the authors demonstrate the mathematical model of the interaction process with the basic surface. The simulation is carried out using the MATLAB software and Simulink extension. The authors also identify the factors that contribute the efficiency reduction of the municipal machine working process.
Results. As a result of the simulation, the authors obtained the graphs of the pile deformation changing and the BWB pressing force changing. When processing the experimental data the researches also obtained the graphs of the brush pile plotted deformation from the BWB contact force and from 2, 3, 4 disks. For further mathematical modeling the authors determined the stiffness of the BWB pile under various loads. Therefore, the paper presents the approximation of the experimental dependence of the brush pile deformation on the pressing force and shows the regression equation.
Conclusion. In conclusion, the authors determined the elastic characteristics of the BWB pile. By the comparing process of the experimental and theoretical data obtained from the mathematical model analysis, the authors found that the difference between them was less than 10%. The obtained results allowed confirming the mathematical model adequacy of the interaction process between the BWB pile and the cleaning surface.
