摘　　要：提出了一种新型纯弯曲耗能阻尼器。通过理论计算给出了耗能钢板与限位移钢板的高度关系,对耗能钢板进行三角形开孔设计,通过理论计算给出单次加载下各尺寸耗能钢板不会产生剪切屈服的最大开孔率,通过数值模拟得到了耗能系数最大时的开孔高度与开孔底边长度。利用有限元软件对影响钢板耗能的几何参数进行力学分析。结果表明:耗能钢板的厚度与限位移钢板的高度对阻尼器的耗能系数影响较大,耗能钢板的宽度和数量对其影响较小。最后通过正交试验给出一个耗能性能强的阻尼器尺寸。In this paper,a new pure bending energy dissipation damper is proposed.Through theoretical calculation gives the height of energy consuming steel plate and limit displacement plate,the energy consuming steel plate triangular hole design,through the theoretical calculation gives the single load size energy consuming steel plate will not produce shear yield maximum opening rate,through numerical simulation of the energy consumption coefficient of the maximum hole height and hole bottom side length.The geometric parameters affecting the energy consumption of steel plate were analyzed using finite element software.The results show that the thickness of energy consuming steel plate and the height of limited displacement steel plate affect the energy consumption coefficient of damper greatly,and the width and quantity of energy consuming steel plate are small.Finally,a strong damper size is given by orthogonal test.
