摘要

为避免既有金属剪切型阻尼器存在的应力集中问题，进一步提高耗能能力，提出一种新型波形软钢阻尼器。利用通用有限元软件建立实体模型，对其进行数值模拟研究。通过对不同波角和厚度、腹板及翼缘材料的强度比对阻尼器力学性能的影响分析可以发现：波角和腹板与翼缘的材料强度比不变时，厚度为5 mm，阻尼器的力学性能最佳；当厚度和腹板与翼缘的材料强度比不变，波角为60°时，阻尼器的力学性能最佳；为充分发挥腹板的耗能作用，腹板与翼缘的材料强度比为1~1.47；理论计算与数值模拟吻合度高，可以通过计算改变相关参数，得到实际工程所需阻尼器。

Abstract

In order to avoid the stress concentration problem of the existing metal shear dampers and further improve the energy dissipation capacity

a new corrugated mild steel damper is proposed in this paper. In this study

a general finite element software is used to establish a solid model and its numerical simulation is carried out. By analyzing the effects of different wave angles and thickness

and the strength ratio of web to flange materials on the mechanical properties of damper

it is found that when the wave angle and the strength ratio of web to flange materials are constant

the damper has the best mechanical properties when the thickness is equal to 5 mm. When the thickness and the strength ratio of web to flange materials are constant

the mechanical properties of the damper are the best when the wave angle is 60 degrees

and the strength ratio of web to flange materials should be between 1 and 1.47 in order to make full use of the energy dissipation effect of web. The theoretical calculation is in good agreement with the numerical simulation

and the damper can be obtained by changing the relevant parameters.
