Abstract
To reduce the transmission of impact energy in a drop forge from the impacting die to the anvil while retaining the deformation efficiency, a double-pad oil film has been developed and tested.
The present paper is focused on the behavior of the oil film under an impulsive load. From the experimental apparatus, the measured pressure distribution over the bottom pad area is compared with that of theoretical results for both small and large gaps.
On the basis of the theoretical analysis of the effect of the bearing parameters on the deformation efficiency and emitted sound pressure, the present double-pad oil film bearing is optimized experimentally. From the recorded signals, it is shown that an optimum point does exist where the emitted sound pressure is minimum.
