Model of a mechatronic control system executive body of ZTM with GPS-intensifier

Abstract

The factors that determine the trends in the development of road technology in the world were analyzed. The characteristics of soil development with the help of an executive body of an earth-moving vehicle (EMT) in real operating conditions were analyzed. An analysis of the working process of the earth-moving vehicle was carried out. The task of increasing the efficiency of the functioning of the earth-moving vehicle when interacting with the ground in a limited time for decision-making was set. The task of increasing the efficiency of the functioning of the earth-moving vehicle with the uncertainty of the input information was set. Information on the performance and cycle times of the bulldozer when using GPS control has been obtained. An analysis of the parameters that form the loading mode of the machine was carried out. A mathematical model of the mechatronic control system of the executive body of an earth-moving machine with a GPS intensifier was developed. This model allows to implement the mode of adaptive optimization of the machine. The tasks of adaptive optimization of the working processes of earth-moving machines, which the mechatronic system solves, have been identified. The mechatronic control system of the executive body of the earthmovingtransport machine, as a system of interconnected functionally complete elements, was presented. A comparative analysis of the data of the traditional control system and the control system with an intensifier was carried out. Analysis of instantaneous point photograms of the position of the dump of the earth-moving vehicle was carried out. Distribution laws of quantities. The structure of the mechatronic feed system of the executive body of the earth-moving machine was constructed. A mathematical model of the mechatronic feed system of the executive body of an earth-moving vehicle with a GPS intensifier was developed. The influence of the GPSintensifier system on the technical and economic indicators of the machine was established. Comparison of experimental and theoretical data to assess the adequacy of the mathematical model of the movement of the machine with the positioning system to real processes was carried out. Analysis of fuel efficiency based on the experimental data was carried out. An experimental study of the influence of the GPS-intensifier system on the technical and economic indicators of the machine was carried out.
