The Common Rail Damages

The Common Rail Damages

2024-10-08

Rail is one of the most important bearing parts of railway system. The traction and braking of trains are realized by the friction between wheels and rail. Therefore, a good rail condition is the prerequisite to ensure the safe and smooth running of trains. However, due to the alternating contact stresses, the rail material often suffers from wear or fatigue damage. As shown in Figure 1, the main types of rail damage include: fatigue crack, peeling, corrugation wear, crushing and rail side wear, which account for more than 80% of all rail damages. With the increase of train running speed and axle load, the rail fatigue and wear problems become increasingly serious, which causes the demands for rail grinding technologies sharply increased.
