The study examines fatigue performance standards for freight car truck components and wheels. Emphasis was given to determining the load environment by analyzing data from 53 test runs. A number of test parameters were varied, such as speed, type of truck, modifications to the suspension system, etc., to determine those parameters having the greatest influence on the severity of the load. Vertical loads were measured at the side-frame-pedestal/roller-bearing-adapter interface and lateral loads were determined at the wheel/rail interface. The cyclic load data are summarized in a series of laod spectra. Factors which must be considered in the development of fatigue performance standards from these spectra include reliability goals, the statistical spread of both load and fatigue strength data, and the philosophy followed in the design of the truck itself.
