Determination of the Stress State Developed within a Non-Cushioned Rail Yoke and the Prediction of the Theoretical Fatigue Life

During service, freight railroad coupling systems experience heavy loading owing to various train actions. For non-cushioned railcars, the primary tensile component utilized to transfer these forces to the draft system is the yoke. The stress state developed within a yoke was analysed using both strain gauge data and non-linear finite-element...
