Summary:The invention relates to the technical field of aircraft structure assembly, in particular to an aircraft structural part assembly positioning point setting method which specifically comprises the steps that firstly, an aircraft structural part is regarded as a rigid body, and an initial positioning point is set according to the 3-2-1 positioning principle; boundary conditions and load conditions are set according to the external load and the gravity of the aircraft structural part in the assembly process, and finite element analysis is conducted on the maximum deformation amount of the aircraft structural part; and if the maximum deformation amount of the aircraft structural part exceeds the assembly tolerance requirement, adding a positioning point at the maximum deformation position, carrying out finite element analysis again, and repeating the step until the maximum deformation amount of the part is smaller than the assembly tolerance requirement. According to the method, the pose accuracy and the shape a
