中文摘要
针对大容量高速逆流色谱仪技术研究与开发,以得到高效、快速、制备量大的分离效果,创新设计了高速逆流色谱仪行星架结构。以仿真软件HyperWorks为平台,建立有限元模型,进行静力学分析及模态分析,验证了设计的合理性及实用性。再基于变密度法中的SIMP插值模型,利用折衷规划法建立了多目标函数的数学模型,对行星架进行结构拓扑优化,寻求材料更合理的分布,并得到了优化结构。在优化结果的基础上重新设计新行星架,再次进行仿真分析,确保结构的可靠性。研究表明：优化后的行星架在各项性能都能满足要求,并且质量降低了13.1%,得到比原始结构更加优良的设计结构。
英文摘要
Aiming at the research and development of large-capacity high-speed countercurrent chromatograph technology, The planet carrier structure of high-speed countercurrent chromatograph was innovatively designed to obtain high-efficiency, rapid and large-volume separation effect. Based on the simulation software HyperWorks, the finite element model was established, and the static analysis and modal analysis were carried out to verify the rationality and practicability reliability of the design. Based on the SIMP interpolation model of variable density method, the mathematical model of multi-objective function is established by using the compromise programming method. The structural topology optimization of the planet carrier is carried out, and the material distribution is more reasonable, and the optimized structure is obtained. Based on the optimization results, the new planet carrier was redesigned, The simulation analysis is carried out again to ensure the reliability of the structure. The research shows that the optimized planet carrier can meet the requirements in various performances, and the quality is reduced by 13.1%, which gets a better design structure than the original structure.
