Integrity management parts of rolling stock in the turnaround time by increasing the quality of recovery of worn surfaces
The results of studies of the effect of dimensional and geometric quality restoration of the worn surfaces of heavy-duty truck parts and components for depot repair of freight cars on their performance in service are adduced inarticle. Describes the sequence of physical and mathematical modeling of wear and fatigue of friction surfaces. Recommendations on the choice of values of the dimensional and geometric parameters processed in the repair of the friction surfacesare presents that can help reduce the wear rate of chassis parts and increase turnaround freight cars.
