Title:
METHOD FOR ESTIMATING FLANGE DISPLACEMENT AMOUNT IN ROTARY MACHINE, PROGRAM FOR IMPLEMENTING SAID METHOD, AND DEVICE FOR IMPLEMENTING SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2023/162384
Kind Code:
A1
Abstract:
In this method for estimating a flange displacement amount, effective three-dimensional coordinate data items are obtained at: a lower first position in a plane contiguous to a lower flange surface of a first supported part; and an upper first position that is located in a plane contiguous to an upper flange surface and that matches with the lower first position in the horizontal direction. The effective three-dimensional coordinate data items at the respective positions are changed such that the effective three-dimensional coordinate data item at the lower first position and the effective three-dimensional coordinate data item at the upper first position match with each other. On the basis of a difference between the vertical-direction position indicated by an effective three-dimensional coordinate data item at an upper target position after coordinate change in the upper flange surface and the vertical-direction position indicated by an effective three-dimensional coordinate data item at a lower target position after coordinate change in the lower flange surface, the amount of vertical-direction displacement is determined for the upper target position and the lower target position when a transition is made from a disengaged state to a fastened state.
