More Information
Summary:The invention belongs to the field of aircraft damage tolerance analysis, and relates to an aircraft wing structure fracture reliability calculation method, which analyzes a wing structure hierarchical relationship according to aircraft wing structure parameters, and the described hierarchical relationship comprises three hierarchies, the first layer forms main key structures of the wing structure, such as a wing body connecting joint structure and a wing wallboard structure, the second layer forms structural parts of the key structures of the wing, such as outer wing 1 #-5 # upper and lower wallboards forming wing wallboards, and the third layer forms fracture key parts of the structural parts, such as spanwise connection of the wing wallboards; according to the hierarchical relationship of the wing structure, load transmission characteristics of different hierarchical structures are analyzed, and the described load transmission characteristics comprise similar/dissimilar single transmission force, similar/d
