摘要

阐述了循环加载下软钢材料应力—应变的理想弹塑性模型、双线性随动强化模型和混合模型

采用有限元软件ANSYS对菱形开洞软钢阻尼器进行数值模拟

得出与所列本构模型相对应的阻尼力滞回曲线

并比较各模型的优缺点及误差存在原因;建立了基于混合模型的90°、60°和45°菱形开洞软钢阻尼器的阻尼力滞回曲线

将其力学参数值与理论分析结果进行比较。分析结果表明:混合模型下

菱形开洞软钢阻尼器的力学参数值和理论计算值一致

且阻尼力滞回曲线能很好地和试验曲线相吻合

验证了混合模型是菱形开洞软钢阻尼器相对比较精确的本构模型。

Abstract

Firstly

the stress-strain relationship of mild steel damper under cyclic loading

i.e.the ideal elastic-plastic model

the bilinear kinematic hardening model and the mixed model are introduced respectively.At the same time

according to the simulation analysis of the mild steel damper with diamond-shaped opening by the finite element software ANSYS

the damping force hysteretic curves of the mild steel damper with diamond-shaped opening under different constitutive models are obtained.Then the advantages and the disadvantages of each model are compared and the reason of errors is analyzed.Secondly

the damping force hysteretic curves of the mild steel dampers with 90°

60°and 45°diamond-shaped opening on the basis of the mixed model are established.And then the mechanical parameters are compared with the results of the theoretical analysis.The analysis results show that the mechanical parameters of the mild steel damper with diamond-shaped opening under the mixed model are consistent with the theoretical results

and the damping force hysteretic curves under the mixed model are consistent with the test curves.All of these demonstrate that the mixed model is a relatively accurate constitutive model of the mild steel damper with diamond-shaped opening.
