| Abstract: | In this paper we descussed a method how to eliminate the effects of additive masses and stiffnesses on the real modal analysis(EMA).Simulated computer tests and application exemples are given to demonstrate the advantages of this method. Finally we discussed the effects of the errors of input databand input ouders of the normal modes on the results. |
