Quality Evaluation Device, Quality Evaluation Method, And Quality Evaluation Program For Rotary Machine
Abstract: This quality evaluation device evaluates the quality of a rotary machine having a rotation unit that is supported by a bearing rotatably with respect to a stationary unit. The device acquires an AE signal from at least one AE sensor provided in the stationary unit, and calculates a rubbing detection index on the basis of the AE signal. The device then estimates the amount of wear of the rotary machine by integrating the rubbing detection index.
