Title:
CONSTRUCTION METHOD OF WATERJET PEENING
Document Type and Number:
Japanese Patent JP2014076539
Kind Code:
A
Abstract:

To control the forced excitation frequency of waterjet peening.

Because the forced excitation frequency of waterjet peening is found out to vary depending on the injection distance, the injection flow rate, and the diameter of a nozzle, based on the natural frequency of waterjet peening construction objects the resonance can be prevented by selecting the injection distance, the injection flow rate, and the diameter of a nozzle of the waterjet peening. The forced excitation frequency of the waterjet peening is determined by fixing an injection receiving plate to a load cell a natural frequency of which is larger enough than the forced excitation frequency, by performing the waterjet peening against the injection receiving plate, and analyzing the load data detected by a load cell.
