There are two stress concentration zones in the locking hooks. On the surface of the hook contacting with the nose rail there are significant contact compressive stress and in the inner side of the hook swerve, stretch stresses.

每个锁闭钩中有两个应力集中区，心轨（或心轨连接铁，或销轴）与锁闭钩接触区以接触压应力状态为主，锁闭钩拐弯处以弯曲造成的拉伸应力状态为主，接触应力集中大于拉伸应力集中；
