Description

Improvement 

Reduce cracks

According to the mechanism of the occurrence and development of fishplate cracks and the theory of fretting fatigue, first of all, it can be considered from the three important factors affecting cracks, namely friction coefficient, slip amplitude and contact pressure, to reduce the probability of cracks.

(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 fastening force between the rail and the fishplate, and the slip amplitude can also be reduced by improving the joint condition and reducing the impact. It is observed that the glued fishplates rarely break, which also shows the influence of controlling the slip amplitude on the life of the fishplates.

(3) Reduce contact pressure. There are many factors that affect the contact pressure. Reducing the contact pressure will reduce the strength of the interaction force between the rail and the fish plate. Operating conditions, axle load, vehicle speed, etc. will have a greater impact on it, some of which must be subjected to working conditions, such as load, vehicle speed, etc., and some can be adjusted by improving the operating conditions, such as maintaining proper Rail seams, good joint maintenance, etc. In addition, the shape of the mating surface of the rail and the fishplate will also affect the contact pressure.
