Problems in application of rivets

Under the working pressure, if the rivets are bent and deformed due to imbalance, they will lead to the frame clamping ball and the all aluminum lantern rivet can not rotate easily. The flexibility of bolt bending in the thin and thick direction is large, so it is only necessary to check the reliability of the bolt in the thin and thick direction. The bending flexibility of the rivet in the thin thickness direction with less toughness is: λ is the flexibility, μ is the height width ratio index, I is the inertia force semicircle, j is to better the bending stiffness of the bolt in the thin thickness direction.

During the second riveting, the lower part of the riveting can be regarded as fixed, and the upper part only has the translation transformation surface and does not rotate. Because the rivet is short, its flexibility is generally lower than that of the strength limit of the matched raw material, so the bolt is a compliance rod. Therefore, when the bolt is removed from the critical value of in-situ stress, the stability check of the bolt is carried out. The groove rivet is the required stable safety performance, which is generally 1.8-3.0, and the in-situ stress of the bolt during working is generally taken as 1.8-3.0. If the value of the ring groove bolt does not meet the above standard, the rivet shows that the reliability of the bolt riveting is not enough, so the reliability should be improved by increasing the bolt thickness s.
