The strength analysis of the diagonal stay of aircraft landing gear based on ANSYS

Abstract

As the landing gear structure is complicated, it is difficult to draw accurate stress and strain distribution through the theoretical calculation. This paper carries on modeling and force analysis to the buffer mechanism of aircraft landing gear, transforms the stress problem dynamic system into static stress problem according to D'Alembert principle and analyzes the diagonal stay of landing gear, and at the same time, analyzes the strength of an aircraft main landing gear by using computer simulation technology and finite element analysis technology, which provides effective basis for damage prediction and practical maintenance. © the authors.
