| 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. |
