DEVELOPMENT OF FATIGUE STANDARDS FOR FREIGHT CAR TRUCK COMPONENTS AND WHEELS

Factors which should be considered in the development of fatigue standards for freight car truck components and wheels are discussed. These standards would be formulated to provide a desired level of operational reliability, and they would be based on the fluctuating loads acting on the components in service. Typical data describing this environmental are presented. Statistical considerations in establishing the margin between the environmental loads and component fatigue strength are also described.
