摘要：

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