Документ Object-oriented design of packaging machines on the principles of mechatronics(2018) Gavva, Oleksandr M.; Kryvoplias-Volodina, Liudmyla; Kokhan, OlenaВ даній роботі наведені результати дослідженнь, які було проведено з метою формування основних принципів об’єктно-орієнтованого проектування пакувальних машин на засадах мехатроніки. Розроблення сучасних мехатронних пакувальних машин потребує розв’язання складних задач в яких враховуються взаємозв’язки між різними складовими, їх реакцію на зовнішні та внутрішні дестабілізуючи фактори. Для розв’язання таких задач запропоновано застосувати методи об’єктно-орієнтованого проектування. Розроблено топологію об’єктно-орієнтованого конструкційно-технологічного проектування пакувальної машини на засадах мехатроніки.

This paper presents the results of research that was conducted with the aim of forming the main principles of object-oriented design of packaging machines based on mechatronics. The development of modern mechatronic packaging machines requires the solving of complex problems, which take into account the interconnections between different components, their reaction to external and internal destabilizing factors. To solve such problems applying of object-oriented design methods was proposed. The topology of the objectoriented design and technological design of a packaging machine on the basis of mechatronics was developed. In the first stage of the design, the analysis of the technological process of transport package formation was carried out, the basis of the SADT basis was formed the hierarchical structure of the machine, the functional and structural models were developed, the decomposition of the service function of the machine was made, the functional and structural scheme of the machine was developed. Functional-structural scheme of the machine for conducting parametric synthesis with the choice of the best or optimal values of geometric, kinematic, dynamic and energy parameters.Документ Dynamics of mechatronic function modules drives of flow technological lines in food production(2018) Kryvoplias-Volodina, Liudmyla; Gavva, Oleksandr M.; Volodin, Sergiy; Hnativ, TarasThe tasks were considered, which are related to the working bodies for the artificial food products movement according to the specified movement law and their positioning in the intermediate positions of the kinematic cycle.Materials and methods. The actuators dynamics characteristics 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. Results and discussion. The analytical dependences for determining the kinematic parameters of the artificial product movement with the mechanism of collision, which is based on the pneumatic actuator, are obtained. The dynamical model of the actuator is mathematically tested and the movement law of the collision mechanism, which is approximated to the optimal speed, is obtained. To analyze the loading process of the working link of the positional actuator, the model of a generalized control system is used, which is limited by the one full cycle of operation of the functional mechatronic module of the packing machine. Such a model allows to describe the overload process, both in the case of full and partial filling of the working cycle. This is important when packing products in different geometric shapes of consumer packaging, which is typical of modern packaging machines. The simulation model of the actuator is theoretically substantiated and confirmed, which has a number of advantages, unlike the existing structures of positional drives in packaging machines. Сalculated difference, during mathematical modeling, of the value of the working time of the output stage of the functional mechatronic module for the processing of the kinematic cycle of the operation of the packaging machine was for the various input parameters of the limit to 7%. The results of the mathematical modeling of dynamics for a positional pneumatic actuator, with the condition of changing the cross section of the exhaust hole, gave the opportunity to obtain the kinematic characteristics of the drive. Conclusions. The results of mathematical modeling for positional pneumatic actuators with the condition of changing the section of the exhaust hole allowed to track all the kinematic characteristics of the actuator.
