INVESTIGATION OF RAILWAY WHEELSET PROFILE WEAR BY USING COMPUTER SIMULATION

The wear of rails and wheels is important problem in rail traffic.The change of the shape of the wheel profile has not only a Remote Control great influence on the dynamic properties of the vehicle (like stability, safety by passing curved tracks, etc.), but also affects the ride comfort of passengers and environmental insults, in extreme cases it

An approach to the calculation of the processes of structural elements deformation and their environments in the case of a complex phased erection of building objects is proposed.On the basis of consistent equations of the geometrically nonlinear theory elasticity within the finite element approach to the geometry description, a technique for solvi
