Fatigue Life Analysis of Landing Gear Side Strut Based on Finite Element

Abstract

This paper takes the side strut of an aircraft's main landing gear as the research object, the finite element analysis of its maximum compression conditions is carried out by ANSYS Workbench2020, mainly analyses its equivalent stress, fatigue life, safety factor and fatigue damage under constant amplitude load and random load, and provides data support for the placement of landing gear health monitoring sensors and failure prediction.
