Several issues in the implementation of vibration analysis of bladed disk

In order to prevent the occurrence of the dangerous forced resonant response of bladed disk in the normal operating conditions, several issues in the implementation of the vibration analysis of bladed disk were discussed. The practical procedures to be used to deal with the issues, which should be considered, for the vibration analysis of bladed disk in the design phase were presented. The analysis results of vibration characteristics of the blade and the disk obtained by use of the procedures match well with the engine test results. The procedures are feasible and can be used to analyze the vibration of bladed disk in the design phase and to eliminate the faults of the bladed disk in service.
