    摘要: Systems and methods for detecting anomalous behavior in one of a fleet of machines are provided. Data regarding a single characteristic representative of operation of the mechanical system is collected from each machine in a fleet. The systems and methods are configured for processing of the data to determine and indicate when significant deviations from normal operating conditions are occurring that represent the departure from normal operation condition by one or more of the machines in the fleet.

    摘要: Systems and methods are provided for monitoring operating machinery, acquiring data regarding characteristic behavior of the machinery being monitored, and processing of the data to determine and indicate when significant deviations from normal operating conditions are occurring that represent maintenance initiating or failure mode events. The method includes learning what normal operating conditions are for a machine of interest by acquiring data during observed normal operation, then calculating detection threshold values based on the acquired data. Finally, real-time monitoring of the machinery of interest during operation is employed, with alarms triggered upon occurrence of a previously-defined number of occurrences of behavior exceeding parameters associated with normal operation behavior.

    摘要: A method of automatically detecting a rolling-element bearing fault in a rotating machine is provided. The method includes receiving, from at least one sensor, a sensor signal that includes at least one frequency, converting the sensor signal to a digital vibration signal, modifying the vibration signal to generate an envelope signal, and applying a transform to the enveloped signal to generate an envelope spectrum. The method uses certain relationships among envelope spectral line amplitudes and their harmonics to detect bearing faults. As such, the method detects a bearing fault without reference to predefined fault frequencies. Systems for implementing the method are also provided.

    摘要: Disclosed is a method for assessing deterioration in a gearbox. Data is obtained from an operating gearbox regarding harmonic frequencies and their related sidebands generated as a consequence of the gearbox operation. In a first embodiment, a Sideband Energy Ratio (SER) is calculated by dividing the amplitude of the sum of sideband signals associated with a harmonic to the amplitude of the harmonic. In a second embodiment, a SER is calculated based on sideband amplitudes associated with adjacent harmonics. The ratio may be monitored over time or compared to one or more values to provide an indication of deterioration.
