%X 飞机起落架扭力臂结构在满足基本结构强度的前提下，应尽量实现轻量化。本文采用Abaqus/CAE中的优化模块对起落架的扭力臂进行拓扑优化，以应变能最大值最小化为控制变量，体积减小为目标，基于条件算法建立优化任务，最终优化后的拓扑结构体积下降49.25%，实现了轻量化的设计需求，为起落架的优化分析提供参考和指导。<br />
On the premise of meeting the basic structural strength, the torsion arm structure of aircraft landing gear should be lightweight as much as possible. In this paper, the optimization module in ABAQUS/CAE is used to optimize the topology of the torsion arm of the landing gear. Taking the minimization of the maximum strain energy as the control variable and the volume reduction as the goal, the optimization task is established based on the conditional algorithm. Finally, the volume of the optimized topology is reduced by 49.25%, which realizes the lightweight design requirements and provides reference and guidance for the optimization analysis of the landing gear.
