Method for identifying dynamic deformation level by mode of blade of aircraft engine, involves constructing three-dimensional dynamic displacement field, and determining deformation field of piece by spatially deriving displacement field

摘要

The method involves associating a set of measurement points of a surface of a piece (3) to pixels of a grid of pixels, and calculating vibrational displacement on the measurement points according to each of sensitivity directions (S). A three-dimensional dynamic displacement field representative of the vibrational movement is constructed on the measurement points, and a dynamic deformation field of the piece is determined by spatially deriving the dynamic displacement field. Independent claims are also included for the following: (1) a system for identifying a dynamic deformation level by a piece mode of an aircraft engine (2) a computer program comprising a set of instructions for implementing a method for identifying a dynamic deformation level by a piece mode of an aircraft engine.
