When carrying out a vibration modal analysis of a structure it is usually assumed that the structure is in vacuo. However as structures become increasingly light and thin walled due to the development of high grade corrosion resistant alloys, this fundamental assumption is becoming increasingly strained. In this paper we will highlight the analysis and the implications of structural/fluid interaction on modal analysis for the purpose of prediction of dynamic response and for vibration health monitoring.
