Abstract As a widely used passive vibration control device, the fluid viscous damper exhibits mechanical performance alteration throughout the entire service life. To explore the mechanical parameter changing mode and reveal the mechanism of performance alteration, experimental and simulation studies were conducted with oil leakage and temperature effects as the main influencing factors. Firstly, cyclic tests and viscousity-temperature analysis were carried out on viscous dampers under different oil leakage levels and ambient temperatures, respectively. Secondly, fluid dynamics simulations were performed to obtain the alternating tendency of the hysteresis performance. Finally, an analytical model reflecting the performance alteration of viscous dampers under combined oil leakage and temperature effects was established and verified. The results show that oil leakage will cause a “zero-force gap” appearing in the hysteresis loop, of which the length is proportional to the leakage level. Temperature increase will lead to a decrease in the damping coefficient, which affects the peak damping force. The established performance alteration model can accurately reflect the changes in mechanical performance of viscous dampers.

Key words： viscous damper oil leakage temperature effect performance alteration model cyclic test；fluid dynamics simulation
