20150012247 | Analysis of Periodic Information in a Signal - A “periodic signal parameter” (PSP) indicates periodic patterns in an autocorrelated vibration waveform and potential faults in a monitored machine. The PSP is calculated based on statistical measures derived from an autocorrelation waveform and characteristics of an associated vibration waveform. The PSP provides an indication of periodicity and a generalization of potential fault, whereas characteristics of the associated waveform indicate severity. A “periodic information plot” (PIP) is derived from a vibration signal processed using two analysis techniques to produce two X-Y graphs of the signal data that share a common X-axis. The PIP is created by correlating the Y-values on the two graphs based on the corresponding X-value. The amplitudes of Y-values in the PIP is derived from the two source graphs by multiplication, taking a ratio, averaging, or keeping the maximum value. | 01-08-2015 |
20140250159 | INTEGER RATIOMETRIC ANALYSIS OF ROTATING ASSETS - A computer-executable ratiometric analysis method determines integer components of a rational number ratio or a close approximation of an irrational number ratio. In one embodiment the method uses a ratio of rotational speeds of two rotating assets in a machine or process, generates a new rational number based on the ratio of speeds, and calculates the integer components of the new rational number. The result is the integer ratio relationship between the initial two rational numbers. The method may be used in machinery analysis applications to determine whether a low-order integer ratio relationship exists between two machinery rotating components. Low-order integer ratio relationships in machinery are generally harmful in related machinery rotating components, and detection of such relationships is an important tool in preventing damage to machinery components. In a more general embodiment the algorithm can be used to determine the closest integer roots of any fractional number where this information would be of interest to an analyst in understanding the fractional number. | 09-04-2014 |

20130207974 | APPARATUS AND METHOD FOR VISUALIZING THE POSITION OF A ROTATING STRUCTURE WITH RESPECT TO A STATIONARY STRUCTURE - A computer-animated graphical model visually conveys the movement and vibration of an entire shaft rotating within its bearings, and the behavior of the shaft at each individual bearing. The model aids a user in (1) visualizing an animated three-dimensional mode shape of a modeled shaft at high speeds, (2) visualizing the alignment state of the bearings of a modeled shaft at slower speeds, (3) visualizing the axial movement of a modeled shaft relative to a stationary component, and (4) visualizing the relationship between a rotating element, such as rotor, and a stationary element, such as a rotor housing, at locations other than the bearing locations. The model enables a user to compare shaft behavior at different operating conditions during a transient event, to see if a shaft is running at a proper position within its bearings, and to see if a shaft is contacting bearing surfaces or is dangerously close to such contact. | 08-15-2013 |
