| 摘 要： | 利用最临界约束准则法对某型飞机机翼主承力结构在强度，位移，扭转角，稳定性和尺寸约束下，以最小重量为目标函数进行了优化，并在实际操作过程中依据机翼结构的复杂性对最临界约束准则法做了相应的修改。结果表明，应用最临界约束准则法进行机翼结构优化时，效率较高，机翼结构重量稳定下降，优化效果明显。

| Abstract: | In this paper, the most critical constraint criterion method is applied to the optimization of the load carrying structure of a wing, under strength, displacement, torsion of wing tip, stability and dimension constraints, choosing weight as objective function. The method is modified according to the complexity of load carrying structure optimization. The results indicate that this method is efficient for wing structure optimization and weight decreases stably with considerable reduction. |
