Sažetak
Modern rail transport with heavy loads and high vehicle speeds requires the adequate fastening of the rail to the base. On most tracks where driving speeds exceed 100 km/h, railway companies use elastic rail fastenings, especially if the tracks are installed on a concrete base. Modern fastening systems are quite complex structures and application of numerical models in the study of fastenings is inevitable. This paper deals with the study of elastic spring clips by three manufacturers: Pandrol, Vossloh and Nabla. One spring clip from each manufacturer, most commonly used on today's railways, was tested. Numerical analysis was conducted in the program ABAQUS on a 3D model of the spring clip, with the same loading conditions as found in exploitation. In order to have reliable models for clarifying the theoretical and practical dilemmas the testing on repeating loading and tensile strength of materials were also done.
