The concepts of model-based fault detection for vibration condition monitoring of rotating machinery are discussed and presented in this paper. The mathematical model presented and fully developed in the earlier works is further modified so it incorporates a typical gear tooth irregularity fault. This fault was simulated on the contact line of the gear model. The results obtained from this analytical model are compared with the ones obtained from a model drive-line. The drive-line consists of a number of rotating parts including an electric motor, a gear system, and a disk brake. The gear system has two meshing spur gears which is equivalent to the analytical model. The comparison of the results are very good as some vibration frequencies of the analytical results correlates with the experimental ones. it is shown that certain vibration frequencies of a real experimental model gear system can be obtained from its analytical counterpart. It is also shown that it is possible to model a typical gear tooth fault by simulating a forcing function as a shock to the modelled system.
