In order to ensure stability, it can be A thin plate 1-7 is added between the square sleeve 1-3 and the limiting plate 1-5. This way of making can cause the following problems:

First, the contact between the pin shaft 1-4 and the limiting plate 1-5 is a line contact, which will cause serious stress concentration, causing the local stress in the hole of the limiting plate to be much greater than that of other parts, and enter yield in advance , will cause severe fatigue damage under dynamic load;

Second, due to the existence of stress concentration, the energy dissipation capacity of the damper is weakened or even fails under the condition of relatively large force;

Third, there is no reliable limit measure along the axial direction of the pin shaft. Under the action of dynamic load, the pin shaft may move along the axial direction, and finally break away from the limit plate 1-5, resulting in the failure of the damper;

Fourth, in order to achieve a better energy dissipation effect, the existing triangular steel plate damper needs to be used in combination with a support with greater stiffness, which is a waste for the support, and the damper must bear The greater the force, the greater the stress concentration.
