The use of modeling of kinematic and dynamic behavior of multi-body and multi-mass systems allows: to avoid critical errors at the early stages of design and thus reduce the cost of product development and reduce the number of physical prototypes created, to determine the mass and dynamic characteristics of complex moving objects and increase the accuracy of calculations of the system's motion parameters taking into account the variable parameters of its volumetric geometric configuration, which is a relevant scientific and technical task. Solving scientific tasks that consist in implementing information technologies to support and make decisions during the synthesis of complex technological systems taking into account the spatial geometry of components is a relevant task for various sectors of the national economy. The tasks of analyzing the kinematics and dynamics of multi-mass and multi-body systems are one of the classical directions in the field of applied mechanics. When modeling the dynamics of multi-mass systems, the finite element method is used, which allows you to explore the concept of the entire system and evaluate its dynamic response in linear and nonlinear settings. Behavioral features can be stored and transferred as input data to FEM analysis for use as dynamic loads, which will provide a more detailed understanding of the system's functioning. The development of modern information systems for solving problems of synthesizing optimal configurations of complex spatial objects requires the construction of mathematical models in automatic mode. At the same time, the process of computer modeling, taking into account the transformation of geometric information and visualization of the obtained solutions, has a creative nature and is one of the most complex and responsible stages in design. The methodology for determining the mass and dynamic characteristics of complex rotating objects has been further developed, taking into account variable parameters of the volumetric geometric configuration, namely special turning devices, boring bars and crankshafts with the location of additional elements that change the weight of the object and the coordinates of the center of gravity, which made it possible to carry out static balancing during the design process and reduce the number of field studies, using the original macro created in the SolidWorks environment, reduce the time for performing operations from 7 to 15 times in combination with reducing errors to a level below 1%, which is an effective means of automating engineering calculations and modeling. In studies of the modeling of the movement of complex multi-mass objects, the methodology for determining the mass and coordinates of the center of gravity of wheeled vehicles has been further developed, taking into account the type and mass of the cargo and its location, as close as possible to their real configuration, which made it possible to make more accurate calculations of the critical parameters of the movement of wheeled vehicles along complex trajectories, and the presence of cargo in the body, especially large-sized cargo, increases the height of the center of gravity, thereby reducing stability by 10%. Further development of the application of SolidWorks information technology for supporting and making decisions at machine-building enterprises in the design and analysis of the movement of complex technical systems, taking into account the spatial shape of the constituent objects and taking into account the variable parameters of the volumetric geometric configuration, which made it possible to achieve balancing accuracy in the range from 0.05 to 0.08 mm at maximum speeds of the product under study and reduce the time for conducting additional experiments. The results of the theoretical and experimental research have been implemented in a new technical solution - a methodology for determining the mass and dynamic characteristics of complex moving objects, which is protected by copyright registration certificates No. 130453 and No. 130457.
The results of the research and individual theoretical provisions have been adopted for implementation at the Private Enterprise "Rezonans-Plast" in Khmelnytskyi and at the Khmelnytskyi Scientific and Research Expert and Forensic Center.
The theoretical and practical results obtained in the dissertation research have been implemented in the educational process of the Department of Mechanical Engineering Technology of Khmelnytskyi National University when teaching the disciplines "Mechanical Engineering Technology" and "Technological Methods for Ensuring Product Quality".
