In a situation in which importance of rail fastening system is growing with increasing the construction of concrete track, an accident of tension clamp(the component of rail fastening system) breaking has been recently occurred. This results from various factors such as field condition, operating agency, running condition, traffic frequency and so on. Thus, the study for the behavior of tension clamp is required. In this paper, an experiment and finite element analysis(FEA) have been performed to analyse the mechanical behavior of tension clamp. The stress and displacement of tension clamp have been analyzed as the clamping force through a laboratory test, and they were compared with FEA results. Furthermore, the stress and displacement of the tension clamp are derived from train load condition applying the verified model, and the fatigue vulnerability of the tension clamp is identified through stress analysis.
