摘要：A method is disclosed for monitoring the vibration of a rotating shaft including,measuring a current shaft position and determining a centroid of the shaft. The currentshaft sector is then determined. The current distance between the centroid and thecurrent shaft position may then be determined. The current distance is compared with apreviously stored maximum distance for that sector, and if greater, the current shaftposition and current distance is stored as the new maximum for that sector. After apredetermined period of time, the maximum displacement between the stored maximumpositions is calculated, which represents the maximum shaft displacement peak to peak.This value may then be visually displayed or automatically monitored by shaft controlcomputers.
