Features of testing bulldozer control system with a GPS intensifier

Problem. The task of positioning the working mechanism of the bulldozer in real time is considered. It has been proven that modern road machines control systems combine achievements in the field of GPS satellite positioning and mechatronic means. A competitive analysis of bulldozer control systems showed that field tests of a traditional bulldozer and a bulldozer with a GPS intensifier have not been conducted before. The task of positioning the working mechanism of the CRM was solved without fully taking into account the diagnostic parameters. Goal. The goal is to establish the influence of the GPS-intensifier system on the technical and economic indicators of the machine and to obtain information about the productivity and duration of the bulldozer's working cycle when using the GPS-intensifier. Methodology. Test and simulation methods for machine control systems using electronic components for earthmoving machines and their equipment were used in the work. A methodology for conducting field tests of a traditional bulldozer and a bulldozer with a GPS intensifier has been developed. Results. The bulldozer control system with GPS intensifier was tested. Comparative analysis and technical and economic substantiation of the research results were carried out. The influence of the GPS-intensifier system on the technical and economic indicators of the machine has been established. Data were obtained on the performance and duration of the bulldozer's work cycle when using the GPS intensifier. The developed method of conducting field tests meets the standards and allows you to fully assess the impact of the new control system on the technical and economic indicators of the bulldozer's work cycle: the duration of the work cycle, total and hourly fuel consumption. Originality. The originality lies in the fact that the using intelligent components of information processing systems allow to increase machine productivity. Field tests of a traditional bulldozer and a bulldozer with a GPS intensifier have not been conducted before. Practical value. The use of a GPS intensifier makes it possible to predict the work of actuators CRM in real time.
