Abstract

Modal analysis is the presentation of the dynamic properties of a system in terms of the contributions due to the independent modes of vibration of the system. This method of analysis is powerful and has become very useful in the analysis of .experimental test data due to recent developments in real time frequency analysis and digital data processing. This paper outlines the recent developments of the method with main emphasis is placed on the use of this approach in analysing the dynamic performance of complex systems and in solving their design problems.
