An improved method of passive thermal control has been proposed in order to operatively assess the technical condition of rolling bearings, based on studying the heating rate of a bearing. The values of the heating rate of ball, roller, and conical rollin... see more

Accumulative roll bonding (ARB) is one of the methods of severe plastic deformation which is relevant for industrial production of sheets. While mechanical properties of several magnesium alloys subjected to the ARB process have been studied, the physical... see more

To improve the strip rolling technology, it is important to know components of the thermal state of both the strip being rolled and the tool used, that is, rolls at each point of different layers of the strip and rolls, in any section of the deformation z... see more

The aim of this study was the determination of the thermal expansion coefficient a (T) in relation to the temperature of the three following aluminium alloys:- Al-6%Zn-3%Mg obtained by conventional ingot casting- Al-0.5%Mg-0.88%Si obtained by Direct ... see more

The scheme of a feeder has been constructed, in which, along with conventional lobed rollers, the pinned or pinned-planked loosening rollers are used. The feeder of such a design achieves both a smooth and uniform feed of cotton to the machine and a chang... see more

In the article the basic theoretical statements of determination of cost of life cycle for the tractive rolling stock as a prerequisite of feasibility study of its update in the modern conditions of economic development are presented.

The row of tasks of theory of vibrations is decided with the use of dependences for analytical determination of coefficient of friction of cachenie.
