Item type:Наукова стаття, Characteristics of Electromechanical Clamping Mechanism with Asynchronous Electric Motor(2020) Prydalnyi, BorysThe study investigates certain operating characteristics of the developed electromechanical actuator of a clamping mechanism for a lathe. The research was conducted using a previously designed special computer program which displays results in the form of graphs. The time dependencies of investigated characteristics have been found and analysed. The theoretical research results facilitate clarification of the peculiarities in operation and creation of the clamping mechanisms with an asynchronous motor. In particular, they contribute to defining appropriate adjustments for specified operating conditions and optimal parameters for structuralelements of mechanisms of this type.Item type:Наукова стаття, Methodology and Tools for Computer-Aided Calculation of Characteristics of Electromechanical Clamping Drive Actuated by Induction Motor(2021) Prydalnyi, Borys; Kuznetsov, Yuriy; Lyshuk, VictorThe article is devoted to solving the problem of determining the parameters of electromechanical drives of clamping mechanism of lathes. The conducted research is directed at the creation of methodology for calculating the main characteristics of a mechanism for workpiece fixation, made on the basis of a new structure with an electromechanical drive. The obtained results were used to create a computer program, which presents the results of calculations in the form ofcharacteristics to time dependency graphs. The use of the developed tools makes it possible to study the mechanism operation as a process consisting of separate strictly defined stages. The obtained model identifies the change in characteristics as they move from one stage of operation to another. The developed research tools also allow defining the optimal adjustment of this type of mechanism.Item type:Наукова стаття, The Concept of Digital Description of Structural Elements of Technical Systems(Springer, Cham, 2025) Prydalnyi, BorysThe paper presents the concept of a new approach to describing the elements of technical system structures, which provides new opportunities for increasing the level of automation of this information processing. This helps to improve the conditions for the initial stages of technical systems development, which relate to the synthesis of their structures and schemes and can currently be carried out only by humans. The paper proposes a methodology for forming a digital description of the characteristics of structural elements that can be combined into a single structure of a certain technical system. This description is based on the creation of a multidimensional vector, which can be further pro- cessed using appropriate mathematical tools, and therefore provides the possi- bility of automating the processing of this information. A methodology for forming vectors of description of structural elements of technical systems is proposed in accordance with the needs of their effective use in algorithms im- plemented by computer programming. The presented approach creates prereq- uisites for automating the processes of creating structures of technical systems, classifying technical systems, efficient storage in the form of a database, effi- cient search by a large number of features, etcItem type:Наукова стаття, Automatic System for Clamping Objects on Rotary Executive Links of Robotics for Safety Critical Application: Solution and Software for Modelling(IEEE, 2024) Prydalnyi, BorysA new method is proposed to improve the mechanisms for object fixation in robots handling critical application objects to ensure safety. The approach recommends utilizing software products developed specificallyfor this purpose. The applications improve the device's prototyping capabilities, visualize its structural schemes, and calculate its individual performance characteristics. The structural diagram of the proposed device complies with the formulated security. recommendations.Item type:Наукова стаття, Improvement of the Automatic Workpiece Clamping Mechanism of Lathes to Expand Technological Capabilities(2023) Prydalnyi, BorysThe force characteristics of actuators of automatic clamping mechanisms determine the forces of clamping workpieces in the spindle assemblies of lathes. It determines the opportunities for clamping the workpieces with a wide range of material characteristics and construction rigidity. The conducted work aims to develop a new method of measurement of the force characteristics of the drive of automatic clamping mechanisms. The measurement issue is solved by implementing the contactless method, which meets the requirements for ensuring the efficient operation of a high-speed spindle assembly. The developed structure provides new opportunities for creating a control system with better possibilities for interactive estimation of the clamping forces. The use of the developed design helps to increase the quality of clamping and, consequently, the productivity ofmachining workpieces with an expanded range of characteristics. The proposed design of the clamp drive does not contain radially movable parts and implements a contactless power supply. It is proposed to control the clamping mechanism by non-contact measurement of the torque at the input link of the mechanical drive in the range of 0–50 N·mItem type:Наукова стаття, Mathematical Model of a Backlash Elimination in the New Clamping Mechanism(2022) Prydalnyi, BorysA theoretical model of the operation of the electromechanical mechanism for clamping cylindrical workpieces and tools on the spindle of metalworking machines during backlash elimination is considered. The considered design of the clamping mechanism is driven by an electric motor and has a number of advantages. On the basis of the model, analytical dependencies are proposed that describe the relationship between the movements of the elements of the mechanism during the first stage of the clamping process. The proposed analytical dependencies allow taking into account stages of the functioning of the mechanism when the forces of dissipative characters prevail in its work. The presented dependencies describe the position of the elements of the mechanism depending on the generalized coordinate, which is the angle of rotation of the electric motor rotor. This allows determining the position of the elements of the mechanism depending on time. The obtained dependencies are a precondition for the development of methods for optimizing the design of mechanisms of this type.
