Outline of Final Research Achievements |
In order to detect cracks occurring in a rotor system, physical models for predicting the vibration characteristics were proposed. One is an integrated multibody - finite element model. Another is a transfer function procedure. Availability of these models for calculating the vibration characteristics of crack occurring were examined. Also, in order to detect cracks occurring in a rotor system, a utilization of machine learning was considered.
