Rail surface damage occurs due to repeated overstressing of the by wheel-rail contact cycles, which is also known as rolling fatigue, and causes regular costly maintenance expenses railways. The preventive strategies reduce rail can be conservative if it not based on measured data. A validated digital model physical system provide data for decision. Interaction between a has evolved at beginnin...

A B S T R A C T Recently, various methods have been proposed to assess the risk of rolling contact fatigue failure by Ekberg, Kabo and Andersson, and in particular, the Dang Van multiaxial fatigue criterion has been suggested in a simple approximate formulation. In this note, it is found that the approximation implied can be very significant; the calculation is improved and corrected, and focus...

The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented. An example calculation of rolling resistance for a polyurethane tire is giv...
