摘要
在橡胶中加入不同层数的芳纶网制成新型的粘弹阻尼器,对其进行了变形相关性试验,将新型粘弹阻尼器与只含有橡胶的原始粘弹阻尼器的滞回曲线作了比较。研究结果表明,新型粘弹阻尼器因硬化提前,导致不同应变下的滞回曲线呈有明显上翘趋势的发散状,且新型粘弹阻尼器的刚度和滞回曲线包围面积都明显增大,能较好改善原始粘弹阻尼器尺寸大小问题。
A new type of viscoelastic damper was added to the rubber to make a new viscoelastic damper,and the deformation correlation test was carried out.The hysteresis curve of the new viscoelastic damper and the original viscoelastic damper containing only rubber was compared.The results show that the new viscoelastic damper is delayed due to hardening,resulting in a hysteresis curve with obvious upward trend under different strains,and the stiffness and hysteresis curve surrounding area of the new viscoelastic damper are obviously increased,which can improve better original viscoelastic damper size issue.
