Summary:A new type of composite viscoelastic damper was made by adding aramid fiber mesh to rubber,and fatigue test,deformation correlation test and frequency correlation test were carried out on the viscoelastic damper.The maximum shear stress,stored shear modulus and equivalent damping ratio of the new damper were studied.The results show that the new composite damper has stable mechanical properties,and the maximum shear stress of the damper is increased.In addition,the fatigue resistance is good.The storage shear modulus and equivalent damping ratio of the damper are greatly affected by the deformation amplitude,and are less affected by the loading frequency.According to the yield point and hardening point in the test,the bilinear and multi-linear models were established by MATLAB,and the simulation results were well fitted with the experimental results.
