This paper proposes a technique for fault–diagnosis of complicated mechanical structures with process of their natural frequency information using artificial neural network. At this initial stage, only location of aligned faults are estimated. The method can evidently be extended to higher dimensions in future research. In order to develop this algorithm, first, natural frequencies of the part, without a fault or with different faults should be identified experimentally. Then, an artificial neural network is constructed and trained with this information to locate the fault. However, due to experimentation limits, a finite element model (FEM) was developed and validated for non–faulty part, then faults were added to the FEM one at a time, and then natural frequencies were numerically calculated for faulty parts. 24 first natural frequencies of the part, block cylinder, all below 5 kHz, were considered as inputs to a neural network model, where its output is the location of the fault. The developed neural network could estimate the location of the fault very accurately.<\div>
