Summary:The invention discloses an iterative analysis method for a cold-state blade profile and a hot-state blade profile. The method comprises the steps that an initial cold-state blade profile serves as a starting point, an initial hot-state blade profile under a temperature load serves as a target, iterative correction of the cold-state blade profile is conducted in combination with the deformation difference value of an initial structure blade profile and the initial hot-state blade profile and a blade profile correction coefficient, and a pre-deformation cold-state blade profile corresponding tothe initial hot-state blade profile is obtained. According to the method, distinguishing characteristics among influence factors such as temperature load, aerodynamic load and structural load can be fully considered, the blade profile deformation rule is analyzed from two perspectives of thermal analysis and deformation analysis, and the blade profile analysis result is more accurate; meanwhile, the initial thermal state
