Abstract
Introduction. The article is devoted to the urgent problem of increasing the operational resource of brushing working equipment and improving the quality of cleaning. The research considers factors which could affect the intensity of the brush working element wearout and, accordingly, the economic losses.
Materials and methods. To represent the connections between the subsystems participating in the working process, the block diagram of the communal machine’s working process is developed,which include the following components : base machine, working equipment, running gear, hydraulic drive, road surface, so this diagram reflects the influence of the microrelief unevenness on the vertical coordinate of the working machine body. In addition, the mathematical model of the interaction process of the microrelief with running and working equipment is presented. Simulation is carried out with the help of the software product MATLAB with the Simulink extension. The unevenness of the microrelief of the roadway is described by recurrent equations, also the correlation functions of the random process are specified.
Results. As a result of the simulation, static and dynamic dependencies of the front and rear axes movement of the base machine, the displacement of the brush body’s axis center from the changing coordinates of the microrelief are established. Similarly,the results of the experiment confirmed the adequacy of the mathematical model of the microrelief’s interaction with the running and working equipment are demonstrated in the research.
Discussion and conclusion. It is concluded that due to the change in the vertical coordinate of the roadway, the pressure on the brush also changes and leads to the change in the frictional force pile on the roadway. Therefore, when the brush hits different obstacles the wearout of the brush increases. With a negative change in the vertical coordinate of the road, the quality of cleaning process is reduced. As can be seen,the hydraulic control system of the communal machine is designed to regulate the position in the vertical plane of the working machine body due to the road and to ensure the optimum value of the clamping force, which would increase the reliability and service of the brush.
