Numerical Analysis for the Dynamic Response Characteristics of the Prestressed Concrete Sleeper

Abstract

Abstract. The Prestressed concrete sleeper (PC sleeper) has many advantages over the wooden sleeper in terms of

Study on Impact Load Response of the Pc Sleeper for Rail Joint Using Three-Dimensional Numerical Analysis Model

“…In the previous study, the numerical analysis with the beam model was executed, and the effect of the impact load due to the rail joint on PC sleeper was evaluated [2]. This previous study indicates that the supporting condition of the PC sleeper has the significant influence on the generated bending moment of the PC sleeper.…”

Commentary: Fatigue Life Assessment Method for Prestressed Concrete Sleepers

“…Finally, the expected value is compared to the limit value for fatigue fracture of prestressed steel (Wakui and Okuda, 1999;Goto et al, 2012Goto et al, , 2017. In that time, it is necessary to sufficiently grasp the influence of each parameter (Watanabe et al, 2016) which is concerning the track and the vehicle condition on expectation value of the tensile fatigue strength of prestressed steel.…”
