Thêm thẻ | Tóm tắt: | The objective of this experimental investigation was evaluating the effective value of the global vibration velocity measurements obtained at four different points of irregular and non-rigid surface, compared to those obtained on a flat and rigid insert used as a reference. All measurements were made in the vertical radial plane of the bearing on the free side of the electric motor of a test module operating under constant working conditions. The normality of the data obtained was evaluated by the Shapiro Wilk test, and the comparison of the samples was carried out by applying the t student test statistic, where it was obtained as a result that the measurements on irregular and non-rigid surfaces are different to those obtained on inserts, providing conclusive evidence that supports the care that must exist when attaching a vibrational analysis sensor on the surface of the machine to be inspected. |
