    Automation of Designing of Cam-and-Lantern Mechanisms in Solidworks
    (Хмельницький національний університет, 2023-01) Kharzhevskyi, V.; Marchenko, M.; Pasichnyk, A.
    To determine the kinematic parameters of the output link (spindle wheel), in particular, to construct diagrams of displacements, velocities and accelerations, you can use the SOLIDWORKS built-in module for calculating kinematics and dynamics - SOLIDWORKS Motion, which allows you to easily create an animation of the mechanism and determine any kinematic parameters his link. In particular, in Fig. 6 shows examples of constructed diagrams of displacements and velocities of the output link

    Synthesis of adjustable mechanism of sewing machine and its kinematic analysis using solidworks
    (Хмельницький національний університет, 2023) Kharzhevskyi, V.; Marchenko, M.; Tkachuk, V.; Bereziuk, O.
    The paper is dedicated to the task of optimal design of eight-linked linkage mechanism of the chain stitch sewing machine, for which it is necessary to solve the problem of the adjustable stroke of the needle. The algorithm and corresponding formulas for conducting a kinematic study of the specified mechanism are presented in the article that allows conducting the optimization design using different criteria. The results of calculations using kinematic research formulas are already given, that made it possible to determine the optimal limits of the needle stroke. The conducted research also took into account the need for optimal values of pressure angles in the links of structural groups of the mechanism, which ensures that they do not jam during the operation of the mechanism, with optimal values of the efficiency, without the loss of its functionality. To verify the correctness of the results obtained by the analytical method, a computer model of the sewing machine mechanism was created in the computer modeling software SOLIDWORKS and its main kinematic characteristics were determined using the Computer-Aided Engineering system SOLIDWORKS Motion. It enabled to determine the values of displacements of the links of the mechanism, its velocities and accelerations, besides it proves the working capacity of the mechanism.

    The practical usage of the path generating linkage mechanisms and dwell mechanisms on their basis
    (UTP University of Science and Technology, 2019-10) Харжевський, В'ячеслав Олександрович; Носко, Павло Леонідович; Марченко, Максим Васильович; Kharzhevskyi, V.; Nosko, P.; Marchenko, M.
    Linkage path generating mechanisms are widely used to drive the various technological machines, and there are mechanisms, working points of which in some part of the trajectory should move along a straight line or along the arc of a circle. Such mechanisms can also provide a dwell of the output link. In particular, such movement of working bodies is necessary in the warp-knitting, combing, winding and other light industry machines, other various fields of modern engineering. But the main problem of the practical usage of such mechanisms is their complicated kinematic synthesis, which can be successfully solved, as shown in the article, by using numerical and analytical kinematic geometry methods.
