中文摘要:
      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。
英文摘要:
      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.
