“…On the other hand, MATLAB is a very powerful calculation tool that, among many other remarkable features, can be used to create matrix-type databases, perform complex calculations, and generates graphs, allowing the creation of graphical interfaces, etc., so undoubtedly we can use it to develop a software for storing vibration analysis data in a database and tools that permit the analysis of data stored in the same software, this being a first step toward the creation of a low-cost "virtual instrument" [9]. This software is limited, in this first development stage, to data acquisition from an Excel spreadsheet, along with the recording and analysis of the acquired data, leaving aside for the time being the capture of the machine's vibrations stage through a transducer, the conditioning of the captured vibrations, as well as the subsequent data acquisition [10,11].…”

In this chapter, the implementation of a "Virtual Instrument" developed in MATLAB/ Simulink® that allows the analysis of the measurement of mechanical vibrations in rotating machines is presented. To accomplish this, we identified the main rotating machines used in industry, the parameters that can be relevant when an analysis of vibration is made, the typical vibration frequency spectra of certain electrical and mechanical failures, the most common regulations employed by the industry with respect to vibration levels in rotating machinery, the tools that are used for vibration analysis, and tools for developing MATLAB software that includes features for storing and managing data from a database, also allowing an analysis and diagnosis of vibration in rotating machines. The development cost for this virtual instrument is very low compared with the tens of thousands of dollars of their equivalents now available in the market.
