On the convergence of stresses in fretting fatigue [PDF]
, 2016 Fretting is a phenomenon that occurs at the contacts of surfaces that are subjected to oscillatory relative movement of small amplitudes. Depending on service conditions, fretting may significantly reduce the service life of a component due to fretting ...

The integrated approach to traction calculation of belt conveyors
Nauchno-tekhnicheskiy vestnik Bryanskogo gosudarstvennogo universiteta, 2018 There was suggested a probabilistic mathematical model of tractive effort distribution among the drives of multidrive belt conveyors. This model takes into account (in an inverted way) speed variations of different points of tractive and carrying belt forms using an artificial increase in probabilistic interval boundaries of slide departures of drive ...
