A Generative Design Method for Typical Structural Parts of Aircraft

Abstract

Typical structural parts of aircraft are the main frame of the aircraft and the carrier of other parts and equipment. Their good design is the basis to ensure the overall performance of aircraft and reduce maintenance costs. If the selection estimation, parameter setting, and model normative inspection of typical structural parts are carried out manually, the design quality and efficiency of large quantities of structural parts will be low especially. In this paper, a generative design method for typical structural parts of aircraft is proposed. Based on the introduction of the design framework, the intelligent design of 3D models for typical structural parts of aircraft is elaborated by taking shear slices of aircraft as an example. It includes the intelligent recommendation of the structural scheme, intelligent design of structural parameters, and intelligent generation of the 3D model. Engineering implementation shows that the proposed method greatly improves the design efficiency and the overall quality of the aircraft.
