“…When calculating the strength of the load-bearing structure of a covered freight car, a finite element method was used, implemented in the SolidWorks Simulation software package (CosmosWorks), (France) [30][31][32]. In this case, the finite-element model of the bearing structure of a covered freight car was formed from spatial isoparametric tetrahedra [33][34][35], whose optimal number was determined by the graphic-analytical method [36][37][38]. The number of elements in the grid was 608,959, nodes -208,409.…”

This paper reports a study into determining the dynamic load and strength of the bearing structure of a covered freight car under operational modes. A feature of the freight car's bearing structure is that the girder beam has a closed cross-section. To reduce the dynamic load of the frame, the girder beam is filled with a material with viscoelastic properties. Such a solution could contribute to the transformation of the kinetic energy of impact (due to jerk, stretching, compression) into work of viscoelastic friction forces, and, consequently, to reducing the load on the bearing structure. To substantiate the proposed improvement, the dynamic load on the bearing structure of a covered freight car was mathematically modeled. The calculation was performed for the case of joint impacts at shunting. The study was carried out in a flat coordinate system. It was established that the maximum accelerations acting on the bearing structure of a covered freight car were about 37 m/s2. The calculated acceleration value is 3.2 % lower than that obtained for the bearing structure of a covered freight car without filler. The results of calculating the strength of the load-bearing structure of a covered freight car are given. In this case, a finite-element method was applied. The maximum equivalent stresses occur in the zones of interaction between the girder beam and the pivot beams, and amount to 319.5 MPa, which is 8 % lower than permissible. The calculation was also performed regarding other operational modes of loading the freight car's bearing structure. The model of the dynamic load on the bearing structure of a covered freight car was verified according to the F-criterion. The research reported here could contribute to designing innovative rolling stock structures, thereby improving the efficiency of their operation.

The presented work is devoted to the improvement of spur gears of the reduction drive for metal-cutting machines according to the criterion of load capacity. A feature of this article is the creation of such a constructive solution, which is aimed at finding a compromise between reducing contact loads in the engagement zone and increasing the complexity and labour intensity of the manufacturing gears process. A procedure for accelerated creation of 3D models of a gear drive and its components using the specialized software application "Shafts and Mechanical Transmissions-3D" in the environment of integrated CAD system KOMPAS-3D is proposed. A study of a new cylindrical gear transmission design with a longitudinal generatrix of axoids, confirmed by the corresponding patent solution is realized. A calculation form for the practical design and manufacture of a new design cylindrical gear is proposed.

“…Одним з поширених методів обробки деталей складної конфігурації без їх закріплення є вібраційна обробка в середовищі вільних абразивів. Завдяки високій ефективності та універсальності вібраційна обробка застосовується в різних сферах виробництва [12][13][14][15][16]. Цей метод дозволяє одночасно обробляти велику кількість деталей, при цьому віброобробка може застосовуватися як на операціях шліфування й зняття задирок так і для полірування, поверхневого зміцнення, підготовки поверхні під покриття.…”

Стаття присвячена проблемам фінішної обробки деталей зі сферичними поверхнями, в тому числі деталей кульових фланцевих кранів «Пробка кульова». Експериментально встановлено, що після вібраційного шліфування та полірування якості поверхонь поліпшилася з 3-го до 8-го класів шорсткості. На підставі досліджень наведені науково обґрунтовані практичні рекомендації щодо підвищення продуктивності технологічних процесів вібраційного шліфування за рахунок скорочення часу обробки шляхом: застосування абразивних гранул в формі П12 та проведення вібраційного шліфування на верстаті контейнер якого розташовано під кутом 45° до осі ординат, перпендикулярній повздовжній осі, що проходить через його центр мас.
