For the first time, a theoretical dependence was obtained to determine the filler concentration of the composite tape. On the basis of this dependence, a composite tape with variable mechanical and tribological properties can be obtained. It is proposed that the composite tape is welded onto the cylindrical surface of the central bowl of the rail truck bolster. The bench tests made it possible to determine the degree of wear of the central bowl of the rail truck bolster by means of a welded composite tape. The wear value of the central bowl of the rail truck bolster with welded-on composite tapes is 0.15–0.18 mm per 10,000 km of a freight car’s mileage. The predicted service life of the central bowl of the rail truck bolster with a welded-on composite tape is 320–420 thousand km. |
