Кафедра "Підйомно-транспортні машини і обладнання" заснована у 1929 році. Першим її очільником став професор Тамарін Д. Н.

Курс "Теорія і будова підйомних машин" в Харківському практичному технологічному інституті викладався ще з 1888 року Вадимом Ерастовичем Тіром.

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

У складі науково-педагогічного колективу кафедри працюють 7 кандидатів технічних наук, з них 5 мають звання доцента.

    Ensuring the reliability and performance criterias of crankshafts
    (Polish Technical Diagnostics Society, 2019) Kotliar, Alexey; Gasanov, Magomediemin; Basova, Yevheniia; Panamariova, Olga; Gubskyi, Sergii
    The issues of efficiency improvement of manufacturing crankshafts in order to ensure their reliability and performance criteria are the priorities in modern production of internal combustion engines. Using the capabilities of modern special grinding machines can improve the quality of machining and obtain the necessary running characteristics of crankshafts. In work the questions connected with development of a method of calculation of rigidity of crankshafts for increase of accuracy of their machining, reliability and performance criteria’s are considered. Based on the proposed methodology, numerical calculations have performed and the possibility of determining the deflections and crankshafts rigidity in any section have been justified. The original construction of the following grinding steady rest for CNC grinding machines specified for machining the crankshaft main bearing journal and connecting rod journal is proposed. The construction design of the device allows for compensating the influence of the cutting force on the elastic strain of the part, depending on the change in its rigidity. The practical value of the research includes in develop recommendations for determining the optimal parameters for the round infeed grinding cycle of the crank pins from the point of view of productivity and accuracy.

    Integrated Approach to Determine Operational Integrity of Crane Metal Structure
    (Budapest University of Technology and Economics, 2019) Gubskyi, Sergii; Yepifanov, Vitalii; Chukhlib, Vitalij; Basova, Yevheniia; Okun, Anton; Ivanova, Maryna; Panamariova, Olga
    One of the elements limiting the crane life cycle and affecting the safety of its operation is a metal structure. Currently, there is no single scientifically-based approach to assess the operational integrity of crane metal structures. The paper deals with issues related to the development of an integrated approach to determine the operational integrity of crane metal structures, based on a combination of numerical methods of calculation (the finite element method and boundary states calculation) and magnetic coercive non-destructive control. The research of the influence of the metal chemical composition, its microstructure and the controlled elements thickness on coercive force values have been carried out. In order to take into account these parameters, it is suggested to use certificated experimental samples with variable cross sections. The practical value of the research is to apply the integrated approach that will eliminate the disadvantages of a separate method, complement these methods, increase the objectivity and accuracy of determining the operational integrity of crane metal structures.
