Abstract
This invention discloses a failure analysis method for composite material wind turbine blades, belonging to the field of wind power generation technology. The method includes: recording environmental information about the failed blade at the site, and collecting background data on the failed blade during its service life; photographing the debris of the failed blade and performing preliminary assembly and reconstruction of the debris; preliminarily determining the loss mode of the failed blade; determining whether the failed blade has special macroscopic damage; conducting a preliminary analysis of the material structure by measuring dimensions and referring to the assembly drawings of relevant components; determining its fracture properties and load-bearing capacity; generating a preliminary analysis report; determining whether the evidence in the preliminary analysis report can explain the cause of the failure; extracting information related to the failure from the preliminary analysis report, connecting them to derive the cause of failure, and proposing improvement measures based on the cause of failure.
