目的：通过介绍耳板的结构优化过程，介绍主观经验判定对结构优化，特别是优化方向确定的积极作用。方法根据耳板的使用条件，在初步设计结构及Ansys计算结果基础上多次迭代，凭借设计经验人为作出优选判断，确定结构改变与优化方向。结果将优化后的结构代入座舱整体模型，对优化结果进行验算，证实耳板优化后满足强度和刚度目标，满足工程实施条件。结论对于像耳板这样结构形式受到诸多限制的，受力复杂的关键部件，常用的优化方法难以保证获得满意的、工程切实可行的结果。采用主观预判优选确定优化方向更容易保证得到一种工程可实施结构。
目的：通過介紹耳闆的結構優化過程，介紹主觀經驗判定對結構優化，特彆是優化方嚮確定的積極作用。方法根據耳闆的使用條件，在初步設計結構及Ansys計算結果基礎上多次迭代，憑藉設計經驗人為作齣優選判斷，確定結構改變與優化方嚮。結果將優化後的結構代入座艙整體模型，對優化結果進行驗算，證實耳闆優化後滿足彊度和剛度目標，滿足工程實施條件。結論對于像耳闆這樣結構形式受到諸多限製的，受力複雜的關鍵部件，常用的優化方法難以保證穫得滿意的、工程切實可行的結果。採用主觀預判優選確定優化方嚮更容易保證得到一種工程可實施結構。

ABSTRACT:Objective To demonstrate the positive effect of subject empirical judgment on structure optimization, especially on direction optimization by introduction of the optimization process of ear-board structure. Methods Considering of the usage condition of ear-board, repeated iterations were made based on the original design and the calculation results by Ansys, the optimum selection was made subjectively based on design experience to determine structure modification and direction optimization. Results The emulation analysis result of the optimized ear-board structure was embedded into the overall cockpit model and the verification of the optimized results showed that the optimized ear-board could meet the requirements of strength and rigidity and satisfy the implementation condition of engineering. Conclusion For the ear-board, as an important part whose structure is restricted to many conditions and whose loading is complex, conventional methods are barely effectual to obtain satisfactory and feasible results. The subjective judgment of direction optimization is more likely to guarantee an implementable structure.
