Abstract | Finite element analysis using a simplified grillage beam model was performed to investigate the effects of the modulus of elasticity of the sleeper, Esleeper and the support modulus, Us on the behaviour of railway turnout sleepers. This study was conducted with the objective of developing a fibre composite sleeper for replacing timber sleepers. The results indicated that the behaviour of turnout sleeper is significantly affected by the changes in Esleeper and Us. A high Esleeper and a low Us generate high bending moments on sleepers with the maximum shear forces almost the same for all the investigated Esleeper and Us. The turnout sleepers tend to undergo greater settlement into the ballast for lower Esleeper and Us. The results show that an Esleeper of 4 GPa is optimal for the development of a fibre composite turnout sleeper as analyses showed that the behaviour of sleepers with this elastic modulus on Us of 20 to 40 MPa are within the specified design codes and standards. |
