This paper presents novel identification schemes to determine model parameters of vibrating structures. A time-domain identification method using transient response is discussed first. Next, a steady-state response method using nonresonant harmonic excitations is considered. An especially attractive method for uniquely identifying the parameters of a structure using both free and forced response is also discussed. Numerical results show that the methods are relatively immune to the presence of damping and many low-frequency modes with repeated or closely spaced frequencies. © 1985 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
