摘要： The present invention relates to a rubbing position identification device for a rotating machine provided with a fixed part and a rotating part. This device is provided with an AE sensor, an axial vibration sensor and a rubbing position identification unit. In the case of rubbing occurring in the rotating machine, the rubbing position identification unit calculates the AE phase, which corresponds to the peak of an envelope determined on the base of change over time in the AE signal detected by the AE sensor, and the axial vibration phase, which corresponds to the high spot position of the rotating part specified on the basis of the change over time in the axial vibration signal detected by the axial vibration sensor, and, on the basis of the phase difference between these, identifies the circumferential-direction position of where rubbing has occurred in the rotating machine.

摘要： In an assembly method for a turbine, measured shape data is acquired by measuring a shape for each of a plurality of casing components in a state in which the plurality of casing components are not fastened to each other. self-weighted state shape data, which is shape data when self-weight is applied, is created for each of the plurality of casing components. A reference shape model is corrected based on a difference between the measured shape data of a target measurement part and the self-weighted state shape data of the target measurement part. By using the corrected shape model, fastened state shape data, which is shape data in a state in which the plurality of casing components are fastened to each other, is estimated for each of the plurality of casing components.

摘要： A method for estimating a flange displacement amount includes determining effective three-dimensional coordinate data at a lower first position of a first supported portion on a surface continuous with a lower flange surface and at an upper first position coincident with the lower first position in a horizontal direction on a surface continuous with an upper flange surface. The effective three-dimensional coordinate data are changed such that the effective three-dimensional coordinate data at the lower first position and the effective three-dimensional coordinate data at the upper first position are coincident with each other. According to a difference between a position in a vertical direction indicated by the effective three-dimensional coordinate data at an upper target position and a position in the vertical direction indicated by the effective three-dimensional coordinate data at a lower target position, displacement amounts of the upper target position and the lower target position are obtained.

摘要： In a method for estimating flange displacement amount, effective three-dimensional coordinate data at a lower first position on a surface continuous with a lower flange surface of a first supported portion and at an upper first position coincident with the lower first position in the horizontal direction on a surface continuous with an upper flange surface are determined. The effective three-dimensional coordinate data at the respective positions are changed such that the effective three-dimensional coordinate data at the lower first position and the effective three-dimensional coordinate data at the upper first position are coincident with each other. In accordance with a difference between a position in a vertical direction indicated by the effective three-dimensional coordinate data at an upper target position on the upper flange surface after a coordinate change and a position in the vertical direction indicated by the effective three-dimensional coordinate data at a lower target position on the lower flange surface after a coordinate change, displacement amounts of the upper target position and the lower target position in the vertical direction when a state changes from an open state to a fastened state are obtained.
