Abstract

Abstract: Through the comprehensive study of static strength, fatigue strength and corrosion, the distribution curve of stress and corrosion damage D of aircraft structure (subscript parts) under static load and the distribution curve of life and corrosion damage D of parts under fatigue load are studied respectively in this paper. According to these two curves and the tolerance, stress value and total fatigue life value of the parts, the tolerance values of the corrosion damage of the parts under static load, the tolerance values of the corrosion damage of the parts under fatigue load and the tolerance values of the corrosion damage of the same parts under static load and fatigue load can be calculated respectively. In addition, the method of using a corrosion damage tolerance value to ensure the safety of the total fatigue life and the total calendar life of the same part, and the matching design and matching use of the total fatigue life and the total calendar life are also studied. These conclusions are applicable to the corrosive parts in atmosphere, ocean, soil and other environments, and solve some unsolved problems in the field of international machinery and corrosion.

Key words: corrosion damage tolerance, calendar life, fatigue life, static load, fatigue load
