The Applied Research Center of Venezuelan CVG Edelca (ARC), has like objectives to give specialized technical support to Edelca's hydrogeneration plants, and ones of its specials objectives are the mechanical vibration metering and acquisition process, as well the later analysis and evaluation of dinamic behavior of the production unit. Considering the needing of data process, analyzing, and final results report timely submission, and considering the company's homemade software development policy, it was required a software tool that could make all these process easily and automatic the post-process step of the collected data. The referenced software was developed under Matlab ver.6.5, using Artificial Neural Networks toolbox, and applying backpropagation supervised learning, with Levenberg-Marquardt optimization. All these results in a quick convergence during ANN training process. The evaluation limits and are obtened by making lineal regression applied to internationals standards's severity curves. Some link has been stablished with Microsoft Excel in order to make easier the human interaction.
