【Abstract】 This paper analyses the engineering feasibility of using the static FEM in the fatigue strength design of the shipunloader’s structure through discussing the difference of infinite fatigue life design and finite fatigue life design and puts forward the calculating work cycle of this structure after considering the shipunloader’s work process.It is useful for crane design engineer to introduce the general fatigue strength design processes of the shipunloaders.更多还原
