高阻尼黏弹性橡胶连梁阻尼器力学性能试验研究
Experimental study on high-damping viscoelastic rubber coupling beam damper
摘要
Abstract
Viscoelastic rubber dampers provide both elasticity and viscidity,as well as satisfactory energy dissipation capacity,which could increase the stiffness and damping of the structures.In this study,tests on the high-damping viscoelastic rubber coupling beam damper were carried out,focusing on the basic mechanical properties of the damper,including the low and high cycle fatigue performance of the viscoelastic rubber damper.Major conclusions obtained from this study are as follows:the high-damping viscoelastic rubber coupling beam damper presents the satisfactory energy dissipation capacity;the storage stiffness,loss stiffness and loss coefficient are obviously affected by the loading amplitude,while the influence of loading frequency is rather negligible;the equivalent damping coefficient presented inversely-proportional relationship with loading amplitude and frequency.The mechanical properties of the damper exhibits notable degradation when subjected to low cycle and high cycle fatigue tests.关键词
