Contact interaction of structural elements has been studied in the case of nominally close (nearly matching) surfaces. A non uniform gap is present between the contacting parts. Contact pressure and contact spot depend on the shape of this gap. Correspondingly so does the stress-strain state of the contacting bodies too. Since the problem is essentially nonlinear, the contact pressure distribution and the contact zones change with the growing loads. The solution is qualitatively different to the case of perfectly matching bodies. For the latter case, the contact pressure is linearly proportional to the load and the contact zone is predefined. Hence for the real structures for which the deviation from the nominal shape is unavoidable the impact of these inaccuracies on the contact pressure distribution and the stress-strain state need to be taken into account. This problem is addressed in the paper by example of elements of stamping dies. Keywords: element of stamping dies, stress-strain state, contact pressure, contact interaction, variational inequalities, Kalker’s variational principle, finite element method, boundary element method

The article is devoted to the actual problem of increasing the performance indicators of machine gear drives. To solve this problem, in the article proposed to use a conchoidal engagement made with a shifting of the reference profile and special contact conditions. A feature of the proposed engagement is that it is less sensitive to manufacturing and assembly errors compared to conventional conchoidal engagement. As a result of theoretical studies, the performance indicators of such an engagement were determined. This made it possible to determine the level of load during further experimental tests of new gears. Contact strength and meshing losses were selected as performance indicators subject to further experimental verification. The ratios of these indicators, calculated for conchoidal spur gears with convex-convex contact, made with a shifting of the reference profile, with similar involute ones, are theoretically determined. Comparative analysis of performance indicators was carried out for gears of involute and conchoidal engagement with the same parameters and shifting of the reference profile. It was found that for experimental conchoidal drives with shifting, the maximum load is 1.2 times higher than that of a similar involute drive with shifting, and the loss in engagement is 21% less. A rational area of application of the new gearing is machine drives for high power transmissions. Keywords: spur gears, conchoidal gearing, profile shift, convex-convex contact, meshing characteristics, teeth surface strength, gearing power loss

Research and experimental studies of stress-strain state of discrete-continual hardened machine parts are presented in this work. This hardening method is distinguished by incorporation of numerous hard spots into the surface layer of one of the bodies. Meanwhile the other part is covered by a continuous corundum layer. Correspondingly, a network of microchannels for lubricant is formed between the bodies. Furthermore the contact loads are intensified in the vicinity of the harder material in the discrete zones. As a result the strength and durability of the loaded parts is increased. The technological parameters of the hardening process have great impact on the resulting characteristics. In particular, this concern the shape of the discrete hardening zones and the material properties of the corundum layer. These factors were varied in stress-strain analyses of the contacting bodies. The dependence of the stress-strain state characteristics on the varied parameters was established. The justified recommendations regarding the technological parameters of the discrete-continual hardening have been developed. Keywords: stress-strain state, discrete-continual hardening, contact interaction, finite element method, contact pressure, machine parts

In the work on the example of parts of dividing dies the calculation-experimental analysis of contact interaction of elements of technological systems is carried out. For this purpose, parametric models of the system of contacting bodies are constructed. Numerical and experimental studies of the stress-strain state and contact interaction of the studied objects were performed in parallel. This makes it possible to establish the features of the distribution of the components of the stress-strain state and the contact pressure in the connection of bodies. The obtained experimental results are the basis for determining the parameters of finite-element models by the criterion of accuracy of numerical modeling of contact interaction of elements of technological systems.

The paper describes the analysis of stress-strain state of complex-shaped bodies that come into contact over surfaces of conforming shape. The intermediate layer placed between these bodies has nonlinear properties depending on the load history. These properties may be associated with the microstructure of the surface layers of the materials of the contacting bodies. They can also be determined by the properties of network structure materials, polymers, rubber-like materials, sprays, gaskets, etc. The effect of these properties on the contact pressure distribution is illustrated by the example of hydraulic pistons. It is established that with the change of properties of intermediate layers the character of contact pressure distribution changes together with the locations of minima and maxima of contact pressure. Moreover, the contact area itself changes size and shape. Peculiarities of the stress-strain state of the contacting bodies are also determined. Possibilities of control of contact pressure distributions and stress-strain state of contacting bodies by special choice of intermediate layer properties are established.

У статті проведений огляд результатів досліджень науковцями щодо системи управління транспортних послуг в нинішній час у Україні та закордоном. На підставі вивченого наукового матеріалу щодо інтегрованого управління якістю транспортних послуг, дано власне визначення даного підходу, запропоновано структуру системи управління якістю транспортних послуг, а також вдосконалену Gap-модель оцінки розходжень за якістю обслуговування клієнтів логістичного провайдера. Сучасний ринок вимагає безперервного поліпшення якості продукції та послуг як найважливішого фактору підвищення конкурентоспроможності, в тому числі логістичних провайдерів. Для вирішення цієї проблеми потрібно мати інтегровані системи управління якістю обслуговування клієнтів, які б враховували вимоги міжнародних стандартів та усіх учасників даного процесу. Проведені дослідження показали, що найбільш доцільним способом підвищення ефективності управління якістю транспортних послуг логістичного провайдера в умовах зростаючої конкуренції є формування інтегрованої системи управління. Як показали дослідження, інтегровані системи управління будуються на основі застосування системного і процесного підходів до управління підприємством, які дозволяють пов’язати в єдине ціле різні процеси і види діяльності підприємства. Інтегроване управління транспортними послугами логістичного провайдера – це, перш за все, мистецтво компромісу, при якому рішення приймаються виходячи із загальної мети з урахуванням інтересів усіх учасників логістичного процесу. При цьому основні труднощі виникають в ситуації, коли сусідні ланки використовують різні принципи організації і планування операцій в ланцюгах поставок.
