Reduce cracks of fish plate:
According to the mechanism of the occurrence and development of fishplate cracks and the theory of fretting fatigue, three important factors that affect crack generation, namely friction coefficient, slip amplitude and contact pressure, can be considered to reduce the probability of crack generation.
(1) Reduce the friction coefficient. This can be achieved through various channels, such as surface treatment, improving surface quality or adding some form of intermediary to the material contact surface.
(2) Reduce the slip amplitude. That is to reduce the amplitude of the relative action between the rail and the fishplate. The slip amplitude can be reduced by adjusting the tightening force between the rail and the fishplate, or by improving the joint condition and reducing the impact effect. It is observed that the glue-bonded fishplates rarely fracture, which also indicates the effect of controlling the slip amplitude on the life of the fishplates.
(3) Reduce the contact pressure. There are many factors affecting the contact pressure, and reducing the contact pressure will reduce the strength of the interaction force between the rail and the fishplate. Working conditions, axle load, vehicle speed, etc. will have a greater impact on it, some of which must be endured under working conditions, such as load, vehicle speed, etc., and some can be adjusted by improving working conditions, such as maintaining proper good rail joints, good joint maintenance, etc. In addition, the shape of the mating surface of the rail and the fishplate will also affect the size of the contact pressure.
