The paper presents the results of fatigue tests for impact endurance on the center sill of a four-axle tank car of 60 cu m capacity with welded automatic coupler supports and a criterion for estimating fatigue strength. The criterion is determined by using a hypothesis of simple linear summation of cumulative damage with a fatigue curve obtained during the testing of welded support-component samples (mockups) of center sills, together with the operational dynamic loading spectrum. The fatigue tests were performed on a special automatic gravity-yard testing unit, which permits the continuous application of longitudinal compression impacts analogous to those sustained by rolling stock in operation--in trains and during switching operations.
