Constructive adaptability of machinery to operate effectively in the full cycle of technological works

Abstract

Introduction: the feasibility of the strategic development of the country in the long term from the point of view of technical support of production areas is considered. Presents an analytical review of designs of technological machines manufacturers, highlighted the work of leading Russian scientists Balovnev V.I., Zorin A.V., Goncharov N.V., Korchagin P.A., Pavlov V.P. and others aimed at solving problems of competitiveness and import substitution of land transport and technological complexes, focused on operation in different sectors of the economy. The increase in the efficiency of technological machines of a wide range of use by constructive refinement by placing in the drive mechanism of the working equipment of the quick-detachable device: quick coupler, which provides the versatility of the base machine, reducing the cost of performing a full cycle of technological works. The modified model of the quick coupler is developed, mathematical, computer modeling and full-scale tests are carried out. Proved the feasibility of the introduction of the indicator variable characterizing the efficiency of the multifunctional machine at the put costs.Methods: the study is based on the analysis of the works of leading domestic and foreign scientists in the field of improving existing technological machines. The theoretical and methodological basis of the study was a systematic approach, probability theory, methods of mathematical analysis, simulation, similarity theory, reliability theory, theory of planning and static processing of results.Results and discussion: a modified model of the quick coupler is developed, a distinctive feature of the design is the model of the unloaded locking mechanism. Simulation modeling, full-scale and bench tests on the level of structural reliability are carried out.Conclusion: operators of technological machines are proposed to supplement the working equipment with a quick coupler with an unloaded locking mechanism that allows to constructively adapt the machines to the effective functioning in the full cycle of technological works by expanding the range of working equipment used and reducing operating costs.
