Kryvoplias-Volodina L. Multicriteria synthesis of mechatronic functional modules of machinesfor food packaging

The dissertation is devoted to the development of new methods of multicriteria synthesis of packaging equipment on the basis of the given characteristics on the basis of a systematic approach to assessing their quality and competitiveness in the structure of food production. The analysis of modern problems of multicriteria synthesis of flowtechnological systems of packing lines of food production. Based on the analysis, the following critical conclusions and perspectives of research are formulated: - the effectiveness of known methods and algorithms of parametric optimization essentially depends on the type and nature of the change in the function of purpose and the presence of a type of restrictions; - the solution of the problem of choosing a rational structure and optimal parameters of the packaging machine is mainly based on the technology of throughdesign (Concurent Technology) — parallel design of a packaging machine with an integrated approach to the selection of criteria for assessing the quality of future packaging equipment for food production; - the consistent solution of the tasks of structural and parametric synthesis and the task of choosing the layout of the packaging machine does not make it possible to comprehensively evaluate potential possibilities of alternative variants of packaging equipment in the early stages of designing is carried out Overall Equipment Effectiveness (ОЕЕ). Тhe description of the program of analytical and experimental research, the synthesis of the algorithm of action to achieve the aim, the substantiation of the object and subject of research, and determined the methods of experimental research. The schemes and models of multistage stepbystep multicriterial synthesis realization on the example of FMM for feeding a roll packaging material for a packing machine with different FSS are presented, the expediency of their use for various criteria of optimization problem is substantiated. The technique of evaluation of packing equipment with the complex criterion of estimation of OEE for various combinations of FMM of the leaststudied group of machines for packing of artificial and finefood products is offered. The actuators dynamics сharacteristics and control system of power part of positional electro-pneumatic actuators were researched. The methods of mathematical and computer modeling, and methods of solving ordinary differential equations and partial differential equations and method of correlation analysis were used. In the obtained results of modeling the kinematic load and the pressure of the working position pneumatic actuator, clearly observed that the inertial component increases in 4 stages (braking), during the narrowing the exhaust section of the working cylinder of the positional pneumatic actuator. Developed alternatives to empirical and semiempirical methods with approaches based on solid state mechanics, Computational Fluid Dynamics (CFD) methods when the NavierStokes or Reynolds equations are solved using numerical methods. The mathematical models with effective method of analysis of productivity of the ejector, as well as separate functional systems of packing machines with nozzle devices are constructed. Definitely the kinematic and dynamic parameters of mechatronic systems in different modes of work during the study: the process of submitting the roll of packing material on the stage of the formation of flexible consumer packaging; of the dosage of the gas and liquid components when processing the packing material and food product; process of transportation of smallpiece products on the stage of the packaging. The approbation of the developed mathematical models of typical functional mechatronic modules of packaging machines of food production on original experimental stands and in industrial conditions confirmed the adequacy of the results of mathematical modeling with deviations within the limits of the error for various technological operations. Тhe applied aspects of production methodology for layout of packing equipment involving functional mechatronic modules for packaging food products in consumer packaging. Describes the technical proposals used during the designing of the new packing equipment and modernization of existing enterprises: LLC “CAMOZZI”, LLC “PAK SERVICE”, LLC “Ponìnkìvska cardboard and paper mill–Ukraine”, LLC “PACKAGING TECHNOLOGY”. The estimated economic effect of the implementation is 231 thousand hryvnia for individual packaging machines and the improvement of functional mechatronic modules.
