Analysis of Linkage Mechanisms with Internal Driving Link

(Advances in Science and Technology Research Journal, 2020-02-05) Kharzhevskyi, Viacheslav; Pashechko, Mykhaylo; Pasika, Viacheslav; Hembara, Nataliya

The linkage mechanisms with internal driving link that are used in many different machines are considered in the paper. The mechanism contains hydraulic cylinder that is hinged to the rack, a rocker arm that is pivotally attached to the driving rod and to the rack. The law of motion of a rod in a hydraulic cylinder was synthesized. The positions, angular velocities and accelerations of the hydraulic cylinder and the rocker arm are analytically determined by the methods of engineering mechanics and the theory of mechanisms and machines. Thus, brief analytical dependencies are obtained. It is shown that the angular accelerations of the hydraulic cylinder and the rocker arm are qualitatively similar to the relative acceleration of the rod. The results of the work can be used in the motion research of hydraulically driven excavator buckets, other lifting and loading, road building machines, in the actuating mechanisms of industrial robots

Analysis of phenomena in real contact spots due to dynamic forcing under tangential micromotion

(2012) Shalapko, Yuriy; Radek, Norbert

Currently, there are two basic concepts concerning surface damage processes: one connected with surface activation, which involves an increase in free energy in a tribological system, and the other connected with surface passivation, when free energy decreases. In oscillating tribocontacts, we observe intensive formation of secondary structures of type I (Fe2O3, Fe3O4) and type II (FeO). Experimental and theoretical studies were conducted to determine the contact between a sphere and a plane, which is the most suitable system for simulating small-amplitude fretting (~ 0–3 microns). In a single point contact, we can observe all types of local surface damage in the radial direction depending on the relative slip amplitude (practically, from ~ 0), from absolutely elastic interaction in the central contact zone to the slip amplitude at the margin of the contact area in micrometers. It is very important to implement numerical and continuous integration of the stick-slip zones and calculate the contact stress and strain of the surface layer. Analyzing the influence of thermal fluctuation on the strength of materials, we can determine the parameters of activation of the surface damage at small-amplitude fretting.

Application of information technologies for modeling the bearing puller screw

(Одеса: ОНУ, 2024) Rudyk O.Yu.; Podchynyuk V.V.; Vasylyshyn A.V.

The study of the behavior of structures can be carried out using an experimental approach. This method allows you to evaluate the behavior of the structure under the influence of various external factors. However, it is expensive and time-consuming. Therefore, in the process of developing high-tech competitive products, leading companies use finite-element modeling, partially replacing an expensive natural experiment with a cheaper and more rational computational one, because the modern level of computer technology allows solving complex problems quite quickly.

Architectural Environment and Emotions

(Shiny World Corporation, 2018) Negay, G.

The article deals with the problem of assessing the emotional potential of the architectural environment with its visual perception. To determine the emotional state of the perceiving subject, it is proposed to use the principle of correspondence of visual information and emotional reaction to it. It is proposed to use a distinctive informational model developed by the author to assess the informative nature of the architectural environment. Unlike probable and statistical model, it is based on the sensitivity of the human visual system to the perception of differences in the elements of the dimensional structure of the architectural environment. The formula for determining the amount of visually perceived information is given. The unit of information measurement is an eler (elementary differences). The method proposed for assessing the harmony of the dimensional structure - the basis for the comfort of visual perception and, as a consequence, the emotional potential of the architectural environment. Such a technique will simplify the psycho-physiological studies of visual perception of the human habitat and its design with predetermined (desired) emotional properties.

Behaviour of nitriding layers for condition of small amplitude fretting

(2007) Drapak, G.M.; Shalapko, Yuriy; Mashovets, N.S.; Radek, Norbert

Purpose: It was explored fretting resistance titanic alloy VT3-1 (Ti-Al6-Cr2-Mo2,5) after low temperature ionic nitriding in unhydrogen environment. Design/methodology/approach: Small amplitude fretting was initiated by the dynamic contact of ball and flat in the regime of the partial slip on edge of spot of contact. A method differs by simplicity and express determination of fretting resistance, namely areas of destruction by action of fretting for part nominally fixed contact - how the functions of cycles of loading. Findings: As a result of fretting the central region of sticking decreasing, and the edge of areas of fretting are increasing. Practical implications: The method of initiation of small amplitude fretting within bounds of preliminary displacement is offered. On the offered method the destruction of titanic alloys is explored at fretting and influencing of ionic nitriding on fretting. By a computation method the work of forces of friction in the area of wear, which in 5..6 times is less for nitriding titanic alloys, is appraised. Originality/value: A method allows defining reactionary power of nitriding layers for small amplitude fretting.

Computer simulation of fracture of the interface implant-bone for total hip prosthesis

(Хмельницький національний університет, 2010) Shalapko, Yuriy; Razuvaeva, Marija; Radek, Norbert

Важливою особливістю моделювання та виготовлення протезів стегна є мінімальна витрата матеріалів, але при цьому вони повинні забезпечити необхідний рівень міцності. В усіх випадках, аутопластичність призводить до зміни умов навантаження кісткок, за яких вони б змогли адаптуватися під час заживлення та експлуатації, а також їх структури і механічних властивостей. Найважливішою умовою ефективної адаптації кістки до ендопротезів є забезпечення довгострокової стабільності імплантату, а саме надійна первинна фіксація. Було зроблено детальний аналіз напруженого стану кісткової тканини в області її контакту з ендопротезом. Ми дійшли висновку, що для всіх з’єднань найбільш небезпечним з точки зору цілісності і можливого фретингу контакту є напруженодеформований стан, за якого можливе відносне зміщення поверхонь у 2– 6 мкм.
