Title:
ROTATIONAL SOLID STATE ESTIMATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/175999
Kind Code:
A1
Abstract:
The purpose of the present invention is to make it possible to estimate the state of a blade by checking, during operation, a rotational solid which continues to operate for a long period of time, which cannot be inspected unless a housing is removed, for which it is difficult to select a pressure point and apply pressure to the pressure point, and for which it is difficult to measure displacement. This rotational solid state estimation system comprises a means 8 for storing pressure distribution data for blade surfaces, displacement measurement points A1–C6, a means 1a for measuring the positions of the displacement measurement points, a means 1b for measuring the rotation speed of the rotational solid, a during-stability-rotation-speed detection means 9, an initial position storage means 2a and a post-elapse position storage means 2b that store during-rotation positions of the displacement measurement points in an initial state and after a predetermined period has elapsed, a means 2c for calculating displacement amount data after the predetermined period has elapsed, a structure model data output means 3 that creates structure models M1–Mn, a means 4 for analyzing the structure models at each rotation speed, a neural network 5 that inputs displacement amount data DA1–DC6, etc., to perform inverse analysis and estimate the state of the rotational solid, and a state display means 6.
