Abstract: A full scale domestic fluid viscous damper was made and the dynamic performance of the damper was tested in detail. The frequency correlation in work frequency range, fatigue performance and job performance at low temperature were inspectedin this experiment. The test results show that the damper mechanics performance stability can achieve the expected design standards. Meanwhile, it also verify the feasibility of the experimental method in the revision industry standard.
Keywords: viscous fluid damper; dynanuc mecharucal characteristics; hysteretic curves
