摘 要: 针对目前C型金属阻尼器在阻尼单元尺寸结构设计方面存在尺寸参数过少,结构过于简单和实际应用 中的效果误差太大等问题。应用分类和系统设计方法,基于参数模型模拟阻尼器在受力载荷下时应力应变情况,运用 ABAQUS对三款不同初始角度的金属阻尼器单元进行了仿真设计,结果表明三款阻尼单元弹塑性过渡阶段、塑性阶段后 的屈服刚度与初始刚度的比值分别在2.8和17左右,与工程应用中的钢材经验计算比值3和20十分接近,符合实际状况。 |

Abstract: There are many problems in design of damping element size structure for C-type metal damper, including too few dimension parameters, over-simpli ed structure, big effect error in practical application, etc. Through the method of classi cation and system design, the stress and strain of the damper are simulated based on the parameter model. Three metal damping elements with different initial angles are designed by using ABAQUS. The results show that the ratios of yield stiffness to initial stiffness of three damping elements are around 2.8 and 17, respectively during and after the elastic-plastic stage, which are very close to the ratios of 3 and 20 in empirical calculation of steel in engineering application, in line with the actual situation. |
