Spring Clip fastener as an important part of the railway system,the primary role is to hold the rail fixed on the sleeper or track plate,adhere to the gauge and restrain the rail to move vertically and horizontally,the vehicle load transfer to the substructure,and supply a certain flexibility and deformation of harmonious ability. According to the usage of rail fastening systems,as well as the mechanical characteristics of the article Spring Clip itself,article Spring Clip occasionally appear crack,crack have many causes,such as excessive deformation under the rail foundation,abnormal wheel load load,wheel/rail system matching problems,car resonance,abnormal abrasion rail,rail fastener system error is too large,and so on. Cracking of High precision spring clip is inevitable,and the cracking rate is acceptable when it insists on a certain low share.However,after Spring Clip cracking,unrestrained parts may be splashed out,hitting vehicle equipment and even pedestrians,causing vehicle damage and even endangering safety. Generally speaking,as an important component of the clip fastener,there are different kinds of the clip.In the process of normal use,the Spring Clip will also fail because of various factors,and cracking is one of the reasons for the Spring Clip failure.
