Analysis of the Fracture Cause of Hexagon Flange Bolts

In fact, the hexagonal flange bolts can be loosened only 100 times in the lateral vibration loosening test, and they need to be repeatedly vibrated one million times in the fatigue strength test. In fact, the reason why it breaks is because the fatigue strength is too large, and if the bolt is loose during use, it will generate a lot of kinetic energy mv2, and under the direct action of this kinetic energy, it will easily lead to If the bolt is damaged, if the time is long, it will cause the fatigue strength of the hexagonal flange bolt to be too large and thus break, so we should pay attention to this when using it.
