This invention relates to the field of blade crown structure technology and discloses a method for designing the oblique cut angle of crowned blades. By defining the direction and magnitude of the oblique cut angle of the crowned blade and defining evaluation parameters for the rationality of the static design of the crowned blade, simulation models of crowned blades with different sizes and directions of oblique cut angles on the crown contact surface are constructed.
