ESTUPINAN P, Edgar; SAN MARTIN, César e CANALES M, Luis. DEVELOPMENT OF A VIRTUAL INSTRUMENT FOR ROTOR DYNAMICS BALANCING. Ingeniare. Rev. chil. ing. [online]. 2006, vol.14, n.2, pp. 146-152. ISSN 0718-3305. http://dx.doi.org/10.4067/S0718-33052006000100008.
This article highlights the importance of rotor balancing like the most important corrective action included in a predictive maintenance program, whose main objective is reducing the vibrations level and its secondary effect in rotary machines. A virtual instrument, based in a data acquisition system has been developed for rotor balancing. With this instrument it is possible to balance rotors in a single or two-plane, using the influence coefficient method or a no phase method. Also the instrument includes a function to determine the vibration severity and a function of vibration analysis with spectral and waveform analysis included. This virtual instrument is useful for rotor balancing in the laboratory as well as in the industry.
