DESIGN CONSIDERATIONS FOR CAR BODY BOLSTER THROUGH SILL-CUSHIONED UNDERFRAME FREIGHT CAR

This paper reviews the changes in freight-car body bolster design brought about by the transition from the rigid underframe car to the modern through-sliding sill hydraulically cushioned cars of the 60's. Space limitations to the body center plate and above the bolster are outlined to describe the design envelope. A theoretical method of structural analysis is then presented for the cushioned underframe body bolster under vertical loading conditions which normally govern the design.
