Introduction to the causes of damage to elastic fasteners

According to the application of the railway fastener system and the force characteristics of the spring itself, the spring occasionally breaks. There are many reasons for the breakage, such as excessive deformation of the foundation under the rail, abnormal wheel load, and matching of the wheel-rail system. Problems, rail resonance, abnormal rail wear, excessive installation error of the fastener system, etc.

The breakage of the elastic strip is inevitable, and it is acceptable to keep the breakage rate at a certain low rate. However, after the elastic strip breaks, the unconstrained part may splash out, which may hit the vehicle equipment or even pedestrians, causing vehicle damage even endanger safety.

Generally speaking, elastic strips are an important component of elastic fasteners, and there are different types of elastic strips. During the normal application of the clip, various factors may cause the clip to fail, and fracture is one of the reasons for the clip to fail.
