摘要

To solve the problems of analysis time consuming and structural parameter uncertainty during the structural optimization of a lunar lander, a structural optimization framework of the lunar lander is proposed. Based on the multi-domain substructure synthesis method, the substructure model of the lunar lander is established and the dynamic analysis efficiency is improved. Based on the interval field method, the uncertain model of structural parameters is established, and the influencing uncertain parameters are obtained through the interval sensitivity analysis. To verify the framework, the structure of the solar wings and the mainbody bulkhead are optimized. The result shows that the framework can significantly improve the efficiency of the structural optimization. By comparing with the deterministic optimization results, it is verified that the structural optimization considering the structural uncertainty can improve the reliability of the analysis results.
