A “Advanced modal test and analysis” program Vibration modal test and analysis plays an increasingly important role in the dynamic analysis and design of structural systems. The methods adopted and developed in the seventies are constantly being improved. The new modal test And parameter identification methods have been put forward one after another. What are the advantages and disadvantages of the various approaches? Can comparisons be made by comparative tests of truly complex structural systems? Arousing great interest and concern in the field of structural dynamics,
