Abstract
The method of novelty detection is applied to diagnose damage in a sim ple simulated lumped-parameter mechanical system. It is shown that the system transmissibility provides a sensitive feature for the detectio n of small stiffness changes. A simple yet successful means of establi shing warning levels is demonstrated.
