| 摘 要： | 金属在进入弹塑性状态后具有良好的滞回特性,且在弹塑性滞回变形过程中能吸收大量能量,因而用来制造不同类型的耗能减震器。提出了椭圆形开口金属阻尼器,并利用有限元软件ABAQUS分析椭圆型、棱形、X形阻尼器在不同开洞率下的滞回性能,将其耗能性能进行对比。结果表明,椭圆形开口金属阻尼器有较好的耗能性能,此分析对以后金属阻尼器的选取也提供了一定的参考。 |
| 关 键 词： | 金属阻尼器 滞回特性 耗能性能 |
HYSTERESIS PERFORMANCE ANALYSIS OF METAL DAMPER |
|
| Abstract: | A metal in plastic state has good hysteretic characteristics,and can absorb a large number of energy in the process of elastic-plastic hysteresis deformation,which can be used to manufacture different types of shock absorbers. It was put forward the oval open metal damper,and dissipative finite element analysis software ABAQUS was used to analyze the hyteretic behaviors of elliptic,prismatic and X type dampers with different hole rate,whose energy consumption performances were compared,and the results show that the oval open metal damper has good energy dissipation performance,which provides a reference for future metal damper selection. |
| Keywords: | metal damper hysteretic behavior energy dissipation performance |
