摘要

System for testing tensile and compressive fatigue loads on the fastening elements of a railway track within the same load cycle, comprising: - a rail section (21, 31) with an opening along the longitudinal axis of its head (22, 32), which in turn has a cut portion (23); - sleepers and fasteners characteristic of a railway track: - a cylindrical bar (24. 44) located across the opening of the head (22. 32), of such a length that the ends of the cylindrical bar (24. 44) are located outside the opening, and such that part of the the cylindrical bar (24. 44) is visible due to the cut portion (23); - a fork (25, 45) comprising a hole, such that the cylindrical bar (24. 44) is placed through said hole: the system being configured to be coupled to a testing machine, by means of an applicator (26) thus allowing the application of tensile and compression forces with different degrees of inclination on the cylindrical bar (24, 44). and therefore, on the rail (21. 31), the sleepers and the fastening elements of the railway track.
