DEVELOPMENT OF A DESIGN-EXPERIMENTAL METHODOLOGY FOR THE PREDICTION OF RELIABLE EXPLOITATION OF FREIGHT RAILWAY CARS

The article is devoted to the front burner problem of effective exploitation of industrial tank-wagons with the presence of residual operation time. The procedure of valuation of tank-cars’ residual operation time for liquid gas transportation was proposed first. Key technical and exploitation param...

Key technical and exploitation parameters of the tank-wagon model 15-1408-10 according to testing loads that simulate loads in real exploitation were approved.
