The method includes the following steps: establishing a three-dimensional finite element model of a to-be-measured rotating blade, and extracting modal parameters of the three-dimensional finite element model; determining the number and axial mounting positions of blade tip timing sensors; constructing a conversion matrix of finite measuring point displacement and an overall strain field; and acquiring blade tip finite position displacement of the rotating blade based on the blade tip timing sensors, and acquiring, by a dynamic strain, dynamic strains of the rotating blade at any moment, on any position and in any direction based on modal processing of the conversion matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-contact dynamic strain field measuring method and system for rotating blade","description":"The present invention discloses a non-contact dynamic strain field measuring method and system for a rotating blade.
