Title:
METHOD FOR ESTIMATING FLANGE DISPLACEMENT OF ROTATING MACHINE, PROGRAM FOR EXECUTING SAID METHOD, AND DEVICE FOR EXECUTING SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2023/162388
Kind Code:
A1
Abstract:
In a method for estimating flange displacement, effective three-dimensional coordinate data is ascertained at a lower first position of a first supported portion in a plane contiguous to a lower flange surface, and an upper first position that matches the lower first position in the horizontal direction in a plane contiguous to an upper flange surface. The effective three-dimensional coordinate data ascertained in the effective coordinate ascertaining step is changed so that the effective three-dimensional coordinate data of the first lower position and the effective three-dimensional coordinate data of the first upper position match. On the basis of the difference between a vertical position indicated by the effective three-dimensional coordinate data at an upper target position in the upper flange surface after the coordinate change and a vertical position indicated by the effective three-dimensional coordinate data at a lower target position in the lower flange surface after the coordinate change, the amount of vertical displacement of the upper target position and the lower target position at the time of the change from an open state to a fastened state is determined.
