Publikováno v: TRANSBALTICA XI: Transportation Science and Technology ISBN: 9783030386658

A scientific method for estimating the effect of dynamic loads arising at the wheel and rail contacts during locomotive movement is proposed, which most accurately describes the behaviour of a real rolling stock and complies with existing standards o
