'ютерне моделювання імплантату для армування стегнової кістки. Пропонується рішення задачі тривимірного моделювання за розробленими кресленнями експериментальних імплантатів для армування стегнових кісток з можливістю варіації їх параметрів згідно з індивідуальними антропометричними особливостями кожного пацієнта. Побудовано тривимірні моделі імплантату, використовуючи 3D-скан стегнової кістки, проведено розрахунок міцності імплантату під впливом ваги людини, з використанням програм Autodesk 3DsMax 2015 та Inventor. Тривимірні моделі імплантатів дають можливість фахівцям медичних закладів підлаштовувати всі необхідні розміри деталі під індивідуальні антропометричні особливості кожного пацієнта. Побудова моделі дає наочне уявлення про те, як саме буде виглядати імплантат з урахуванням тих чи інших параметрів. Тривимірне моделювання може дати корисну інформацію про поведінку імплантату і взаємодіючих з ним структур організму в «нештатних» ситуаціях, обумовлених, наприклад навантаженням та деформацією, що веде до перелому. Ця інформація дозволяє сформулювати додаткове, до медичних, «технічне» обґрунтування правильного вибору та точної установки імплантату.Ключові слова: тривимірне моделювання, проксимальний відділ стегнової кістки, профілактичне армування, імплантати, аналіз на міцність, розрахунок навантажень O.

The decision of the problem of three-dimensional modeling according to the developed drawings of experimental implants for the reinforcement of femoral bones with the possibility of variation of their parameters according to individual anthropometric features of each patient is proposed. Three-dimensional models of the implant were constructed using a 3D scan of the femur. The calculation of the strength of the implant under the influence of human weight, using the programs Autodesk 3DsMax 2015 and Inventor was carried out. Three-dimensional implant models enable medical professionals to adjust all the required dimensions of the item to the individual anthropometric features of each patient. The construction of the model gives a clear idea of how the implant will look, taking into account those or other parameters. Three-dimensional modeling can provide useful information on the behavior of the implant and the interacting structures of the body in the "unusual" situations caused by the load and deformation leading to a fracture. This information allows us to formulate an additional medical "technical" justification for the correct choice and accurate installation of the implant.

Development of modem power engineering follows the line of continuous increase in speed, coefficient of corrosive action and capacity of units. Gears and reducers are responsible parts of modem machinery and occupy an important place in the domestic power engineering construction. Durability and wear resistance of gears, apart from the design factors, also depends on the technological methods of treatment. The final stage of production of such wheels is the operation of gear grinding. In the process of gear grinding in a thin surface ball there are complex thermomechanical processes. As a result of short-time heating to high temperatures, structural transformations, burns, and in some cases even micro- and macro-thicknesses occur in such a surface bail. In addition, there are cases of making tooth wheels with adjacent defects grinding (for example, the appearance of the surface of the ball teeth of large tensioning forces), which reduces the life of the work, and in some cases causes a breakdown of the teeth in operating conditions. Development of effective measures to ensure the quality of the surface of the ball on the operation of grinding baggage in part depends on the possibility of predicting (or calculation) of temperatures and residual loads on the depth of the cemented teeth ball. The method of calculation of internal surplus Toads occurring during grinding of wheels with cemented steels is suggested. On the basis of the performed calculations and experiments the ways to improve the quality of production of working surfaces of gears, which are used in the wits of thermal and nuclear power plants are suggested and grounded.

The article considers the urgency of creating a tourist application for the city. Developed a mobile application that will collect information about the sights of the city of Odessa. The architecture of the mobile application «Tourist guide for Odessa», its structure and description of classes is considered. Described navigation on the application and the result of testing on emulators. A mobile application is an excellent solution for information to be always at hand. Mobile applications are a tool for the development of tourism and attract investment. The developed application is aimed at hiking in the city. The main object of the application will be architectural landmarks of the city and historically important places with detailed information about them. The user was offered several variants of hiking trails in order to remember our city in all its glory and grandeur.

The article is devoted to designing a biocompatible human ear implant with the further possibility of its bioprinting. The paper considers 3D technologies used in medicine, the latest trends in the development of 3D bioprinters. The methods of modeling the human ear using the Artec Spider 3D scanner and the patient's digital image are considered. Using these methods, 3D modeling in the software package Autodesk 3ds Max and a solid 3D model of the human ear. 3D-bioprinting is an offensive step for the 3D-friend, which is widely to be visualized in medical. Through the rapid creation of high-precision products, taking into account the specifics of anatomy and pathology of the patient - improve the efficiency and quality of medical care. It will save a lot of lives and, possibly, in time, will improve the organs themselves. Getting a good three-dimensional model plays a big role in the correct form of the printed ears of the patient.
