Abstract

  Results of FFT analysis of the noise generated during the shake-out of iron castings showed that the power spectrum prior to actual shake-out starting is close to that of the consolidated vibration of the shake-out machine and molding flask. On the other hand, after shake-out completes, the power spectrum closely resembles to the characteristic frequency of the molding flask. Based upon the above results, a formula to allow the relationship between the time and the power spectrum was obtained by approximation. Using the formula obtained, the time when the shake-out starts and the time it ends are calculated, and the actual shake-out time can be estimated.
