Stability and Strength Analysis of Aircraft Landing Gear Support Rods
[Purposes]The landing gear of an aircraft is one of the most important components.Due to the large strength surplus of the landing gear support rods,it is necessary to conduct relevant research on its structure to achieve weight reduction.[Methods]This article uses ABAQUS software to perform linear buckling analysis and static strength analysis on the cylindrical structure of aircraft landing gear support rods.According to the result cloud map,it can be seen that the material strength surplus is large.Consid-ering fully utilizing the material's performance and reducing the overall weight of the landing gear,three methods are used to improve the structure of the support rods.[Findings]According to the simulation analysis results,it can be seen that the belly plate filled support rod structure cannot achieve weight re-duction design for landing gear support rods.The corrugated filled support rod structure and honeycomb filled structure still have good mechanical properties on the basis of reducing the weight of landing gear support rods.[Conclusions]The corrugated filled support rod structure and honeycomb filled structure can achieve weight reduction on the basis of meeting the stability and strength conditions of the support rod,and provide certain ideas for subsequent research and engineering applications such as lightweight design of landing gear.
