摘要： A condition monitoring system receives vibration data from one or more sensors that are attached to a machine having cyclical components, such as a gearbox. Samples (431, 432, 433, 434 435, 436, 437, 438) of the vibration data are time stamped based on a cycle time of a component focused on. A number of segments (410, 412, 414) are created each with a time extension based on the cycle time of the component focused on. The samples are split into the segments (410, 412, 414) based on matching a sample's time stamp to be within a segment's time extension. For each segment, the samples of the segment are summed and divided by the number of samples split into the segment. This will allow a degree of speed fluctuation of a monitored machine. The results are presented as a cycle of the component focused on.
