Improving the Performance of Rail Fastening System Evaluation

Regarding Japanese test methods for rail fastening systems, it was confirmed that the rail tilting angle obtained in a biaxial loading test did not agree with the angle calculated using a conventional rail tilting analysis model. To address this problem, a calculation method for biaxial loading using an FEM analysis model, where various stiffness properties regarding the rail fastening systems can be expressed as non-linearity, was proposed and its validity was confirmed. In addition, a study on the optimization of a method for testing rail restraint was carried out through experimental validation under various conditions.
