Journal ArticleDOI
Wear in Partial Slip Contact
TL;DR: In this article, an analytical method that evaluates the evolution of stress and surface profile in fretting under the partial slip conditions is presented, based on two scales of time: time for one cycle of the oscillating tangential force and time corresponding to the number of cycles.
Journal ArticleDOI
Freight car models and their computer-aided dynamic analysis
Roman Kovalev,Nikolay Lysikov,Gennady Mikheev,Dmitry Pogorelov,Vitaly Simonov,Vladislav Yazykov,Sergey Zakharov,Ilya Zharov,Irina Goryacheva,Sergey Soshenkov,Elena Torskaya +10 more
TL;DR: In this article, computer models of freight cars with three-piece and Y25 bogies are considered and compared and efficient numeric methods for simulation of vehicle models in the presence of frictional contacts are discussed.
Journal ArticleDOI
Contact characteristics of a rolling/sliding cylinder and a viscoelastic layer bonded to an elastic substrate
Irina Goryacheva,Farshid Sadeghi +1 more
TL;DR: In this article, the rolling or sliding contact of an elastic cylinder and a layered foundation has been investigated, and it has been established that the contact characteristics (i.e. pressure distribution, size and displacement of the contact zone and indentation of the cylinder into the viscoelastic layer) depend on three non-dimensional parameters.
Journal ArticleDOI
Adhesive interaction of elastic bodies
TL;DR: In this article, a unified formulation of the axisymmetric problem of adhesion between elastic bodies and a method of solving it is presented and the loss of energy in an approach/separation cycle between the bodies as a function of the basic parameters of the problem is investigated analytically and numerically.
Journal ArticleDOI
Rolling contact fatigue defects in freight car wheels
Sergey Zakharov,Irina Goryacheva +1 more
TL;DR: In this paper, the influence of creep velocities and the coefficient of friction on the contact stress distribution of railway wheels is studied and results of theoretic studies and modeling of the defect formation are presented and discussed.
