Paper Abstract

A new optimization method based on the fatigue life of multi-body structure is proposed in this paper with the computeraided engineering software. Taking the nose landing gear of some aero transports as an example, the loading history of the nose landing gear is firstly gained by the multi-body dynamics simulation, and then the fatigue life is predicted through the finite element method and fatigue analysis. In accordance with the forecasting results, the weakest parts of the components are identified, and then they are optimized based on the fatigue life to lengthen the fatigue life of structural weaknesses thus to the fatigue lives of the whole structures.
