Although railway clips are small railway parts, they are an important part of the track. Because of their high demand, about 7,000 pieces per kilometer, their reliability is directly related to the safety of driving. When railway clips work, they mainly use the bending deformation performance of the material. The processing is relatively simple and the cost is often low. However, due to the opening for bolt fastening, stress concentration is likely to occur in this part, and the large surface bending moment is precisely the weakening of the section.
