中文摘要:
      对某新型仪器舱的拓扑优化设计进行研究。使用HyperMesh建立仪器舱的拓扑优化模型,利用OptiStruct对设计空间进行拓扑优化求解,以减重70%为目标,得到基于加权刚度最大化的设计方案,并采用3D打印制造了仪器舱的聚乳酸树脂样件。对比试验表明,基于加权刚度最优的设计方案,在质量最轻的前提下,实测+X支架刚度和-X支架刚度达到最优,实现了初始设计目标。
英文摘要:
      The topology optimization design of a new type of instrument cabin is studied. The topology optimization model of the instrument cabin is built by HyperMesh. The topological optimization of the design space is solved by OptiStruct. To reduce the weight by 70%, the design scheme based on weighted stiffness maximization is obtained, and the polylactic acid resin sample of the instrument cabin is prepared by 3D printing. Comparison test shows that adopting the optimal design scheme based on weighted stiffness, with the minimum weight, the measured stiffness of mounting bracket in the X direction and -X direction are the highest, which achieves the initial design goal.
