Research on Lightweight Configuration of Aircraft Landing Gear Torque Arm Based on Abaqus
Initially,a numerical analysis model for the torque link of the landing gear of a specific large aircraft was developed,focusing on the load-bearing characteristics and the interaction between components.Subsequently,a topology optimization of the overall model was performed based on a conditional algorithm,targeting a reduction in weight following an overall strength assessment.In the next phase,a three-dimensional model of the lightweight torque link,exhibiting an optimized stress distribution,was reconstructed based on the results from the topology optimization.Additionally,the investigation into the stress distribution patterns and stiffness characteristics was carried out,considering variations in the angle between the upper and lower torque links according to the refined model.Ultimately,the optimization and numerical analysis findings indicated a 46.6%reduction in the volume of the structural material of the optimized torque link,which significantly decreased its weight and satisfactorily addressed the design objective of lightweighting the aircraft landing gear.
