Abstract:
      The influence of test conditions on the dynamic characteristics of the fluid-elastomeric damper was investigated.The test results showed that the energy loss of the damping fluid accounted for more than 86.3% of the energy loss of the fluid-elastomeric damper，and the energy loss capacity of the fluid-elastomeric damper increased significantly with the increase of shear amplitude and frequency.The elastic stiffness and damping stiffness of the fluid-elastomeric damper decreased with the increase of shear amplitude and increased with the increase of shear frequency.When the shear amplitude increased from 0.2 mm to 1.5 mm，the damping stiffness of the fluid-elastomeric decreased by 42.7%.When the shear frequency increased from 0.5 Hz to 4 Hz，the damping stiffness of the fluid-elastomeric increased from 2 213 N·mm-1 to 5 802 N·mm-1.
