Від 2005 року кафедра має назву "Інформаційні технології та системи колісних і гусеничних машин ім. О. О. Морозова", первісна назва – кафедра "Колісні та гусеничні машини".

Кафедра "Колісні та гусеничні машини" створена 2 грудня 1972 року. Ініціатором заснування кафедри був один із творців легендарного танка Т-34, головний конструктор ряду серійних танків (Т-44, Т-54, Т-64) і їхніх модифікацій, доктор технічних наук Олександр Олександрович Морозов, першим завідувачем – доктор технічних наук, професор Віталій Прокопович Аврамов.

Кафедра входить до складу Навчально-наукового інституту механічної інженерії і транспорту Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 2 доктора технічних наук, 4 кандидата технічних наук; 2 співробітника мають звання професора, 4 – доцента.

    A refined technique for the automated determination of friction losses in the toothing of multithreaded transmissions with differential mechanisms and planetary gears
    (2017) Volontsevich, Dmitriy Olegovich; Veretennikov, Ievgenii; Kostianyk, I.; Pasechnyi, S.
    Multithreaded transmissions, which using differential mechanisms for separating and summing up power flows, have been widely used in the transmissions of transport vehicles and special drives. The quality of such transmissions and the magnitude of frictional losses in the toothing significantly depend on the adopted kinematic scheme and the ratio of powers passing through the corresponding links of the differential mechanisms. With the existing automated analysis and synthesis of such transmissions, a matrix approach has recently been widely used. The proposed work provides a refined technique for the automated determination of friction losses in the toothing of multithreaded transmissions which containing differential mechanisms and planetary gears. It makes it possible to more accurately determine friction losses in the toothing and at the same time preserves the linear structure of the system of equations, which permit to continue using the matrix approach to analyze and synthesize such transmissions. Examples are given for the formation of equations systems describing the force interaction between the elements of the scheme for all variants of the links commutation of planetary rows operating as three-link differential mechanisms and planetary gears with one stopped link. The work is based on the analysis of existing methods for determining friction losses in the toothing and personal practical experience in the design and study of multithreaded stepped and stepless transmissions. The received results allow to apply the offered technique in the modern program complexes focused on the automated analysis and synthesis of multithread transmissions with use of the matrix approach. This makes it possible to significantly reduce the time to develop new multithreaded transmissions and increase their technical characteristics.

    Parametric synthesis of the digital invariant stabilizer for a non-stationary object
    (Національний технічний університет "Харківський політехнічний інститут", 2020) Aleksandrov, Eu.; Aleksandrova, T. Ye.; Kostianyk, I.
    Two methods are considered for choosing the values of the variable parameters of the digital stabilizer for a non-stationary object, which ensures the invariance of the closed stabilization system to the action of external disturbances. The comparative analysis of the considered methods was carried out in order to identify their advantages and disadvantages. As an example, it is considered the problem of parametric synthesis of the digital stabilizer of the C5M cosmic stage of the Cyclone-3 carrier rocket as part of the program for the modernization of these objects created in the late 70s by the joint efforts of the Yuzhnoye Design Bureau and NPO Hartron, which contain an analog stabilization system and operating to date. It is concluded about advisability to replace the C5M analog stage stabilizer with the digital stabilizer in order to improve the quality of the stabilized process of the stage in the active part of the flight trajectory. It is shown that both methods considered in the article lead to the creation of the digital stabilizer that provides a significant reduction in the static error of the closed digital stabilization system of the cosmic stage of the carrier rocket and an increase in the quality of stabilization process.
