Title:
METHOD AND DEVICE FOR ROTATION ANALYSIS OF ROTATING BODY
Document Type and Number:
WIPO Patent Application WO/2018/225491
Kind Code:
A1
Abstract:
Provided is a method for rotation analysis on a rotating body, which enables both greater analysis accuracy and calculation cost reduction. The surface shape of a rotating body T comprises a plurality of minimum unit M repeatedly disposed in the circumferential direction CD. The method involves: steps (S100, S101) for acquiring a model wherein a computational grid in one partial area Ar1 is more finely configured than a computational grid in another partial area Ar2; a step (S103) for performing a rotation analysis process by rotating the rotating body T by an angle corresponding to N minimum units (N being a natural number of at least 1); and a step (S105) for performing a mapping process for copying the physical quantities of the computational grid following the rotation analysis process to a corresponding computational grid at the start of the rotation. The rotation analysis process (S103) using post-mapping computational grid and the post-rotation-analysis mapping process (S105) are performed repeatedly until a prescribed condition for ending the analysis is met.
