Abstract:
The double
freedom degree mechanical model with damping for forging hammers
is set up in this paper, and the influences of the stiffness and
damping ratio of the liquid damper on the vibration-absorbing
ability are discussed. Especially, the optimum design for
stiffness and damping ratio of the damper is carried out by the
full-displacement method and direct experiment method. The
results of calculation and experiment show that the stiffness
and damping ratio have great effect on the performance of the
isolater.
