Abstract
The paper considers an issue of extending the service life of eight-axle tank cars for alkylbenzenesulfonic acid by modernization of car design. The modernization included technical diagnostics of cars with basic design, repair or replacement of car parts and equipment, calculations and tests of modernized car design. During the technical diagnostics of cars the authors carried out a statistical analysis of failures, determined a speed of corrosion of car elements in operation and predicted a residual service life. On the basis of results of technical diagnostics the authors created a finite element model of the car, formulated normative calculations and carried out necessary tests on natural samples of cars. As a result, calculations and tests confirmed the reliability of gained data, justified the service life of the modernized car design.
