This study represents a measurement uncertainty model for rotor vibration amplitudemeasuring system. The measuring system is established to provide a simple way forrotor vibration measurement and consists of a combination of different sensors. Asimple data acquisition software is resolved using LabVIEW. This program enablesdisplaying and recording the directly measured data. Type-A and type-B uncertaintiesare estimated in detail for measuring results. The two different types are combined toevaluate the deviation of readings resulted from several sources. The overall systemaccuracy for rotor vibration amplitude is derived from combining uncertainties of thetwo measured perpendicular vibration displacements. An error bar is provided foreach reading to indicate the possible deviation with 95 % level of confidence.Uncertainty detailed calculation for rotor vibration amplitude measuring system iscomputed as a function of the directly measured values. |
