Information × Registration Number 0216U003798, 0113U002065 , R & D reports Title Mechanics of cyclic frictional contact with a relative micro-nano motion and subsequent destruction surfaces popup.stage_title Head Kurskoi Volodymyr Sergijovych, Registration Date 18-02-2016 Organization Khmelnytskiy National University popup.description2 Subject of research - the process of strengthening material and its interaction with the contact tangential microdisplacements. The object of the research project - nominally still-surface at the nodes of machine parts and structures. The aim is to develop research based on computer modeling of the dynamics of frictional interaction methods to increase the dynamic integrity responsible nominally-fixed joints in mechanical and biomechanical systems in terms of small-amplitude fretting through the creation of surface modification coatings with high specific surface area of concentrated high-impact methods and regular local surface finish. Experimental studies were carried out under the "ball-plane", "plane-plane" in a wide range of normal pressures, frequencies and amplitudes of vibration disturbance. Research microgeometry and definition of quantitative characteristics microdamage carried out by laser scanning of surfaces in three dimensions. Complete coverage of construction materials created by selective laser welding based alloys CoCrMo and AlSi30. The model identification fretting-contact surfaces and contact surfaces of individual nominally-fixed connections (NNZ) with probability distribution geometrical parameters of trace elements (DOE). Modulation methods of mathematical and computer simulation model developed evolutionary dynamic behavior of contact.
