Abstract
The regularities of the propagation of elastic vibrations in rails under buffing loading were studied for developing the technique for testing wheel pairs of freight cars in motion. Using strain gauges glued on both sides of a rail web and a fast Dinamika-1 strain-gauging system, vertical and horizontal deformations were measured. The parameters of elastic vibrations of a rail have been experimentally determined. The presence of two rail vibration modes (symmetric and antisymmetric) and the dependence of their amplitude on the misalignment of the buffing loading point have been established.
