In order to solve the problems of tedious measurement process and difficult debugging of aeropropeller blade shot peening intensity,this paper analyzes the defects and shortcomings of the existing technology,and puts forward an automatic measurement solution of shot peening intensity based on theory of inventive problem solving(TRIZ).Based on the reverse action principle of the conflict resolution method in TRIZ theory,the existing shot peening intensity measuring instrument is optimized.The automatic measurement is realized by integrating the strain gauge sensor in the base of the Almen test strip to calculate the shot peening intensity in real time.In addition,based on this solution,an automatic measurement system for the shot peening intensity of the aeropropeller blade is designed,and the innovative design of the test method is realized.
