Abstract

This paper proposes a bi-objective optimization method for the small satellite components layout optimization design, considering mass characteristics and fundamental frequency characteristics. Firstly,

φ

function is used to describe the geometry and position relationships between components, effectively addressing the non-overlap constraints among them. Then, the finite element method is used to calculate the stiffness and mass of the satellite load-bearing board to determine the fundamental frequency of the satellite. In addition, the paper designs a novel bi-objective optimization algorithm combined Diverse Gradient Optimization (DGO) algorithm with the Smart Normal Constraint (SNC) method, which simplifies the complex gradient calculation through semi-analytical sensitivity analysis. Finally, numerical examples validate the applicability and rationality of the proposed optimization method in solving bi-objective satellite components layout problems. The results show that the method can provide effective solutions for the layout design of small satellite components while considering both mass characteristics and fundamental frequency characteristics optimization.

基于基频最大化的小卫星元件布局设计

提出了一种考虑质量特性和基频特性的小卫星部件布局优化设计双目标优化方法。首先，利用φ函数描述零件之间的几何关系和位置关系，有效解决零件之间的不重叠约束；然后，采用有限元法计算卫星承重板的刚度和质量，确定卫星的基频；此外，本文设计了一种将多元梯度优化（DGO）算法与智能正态约束（SNC）方法相结合的新型双目标优化算法，通过半解析灵敏度分析简化了复杂的梯度计算。最后，通过数值算例验证了所提优化方法在求解双目标卫星部件布局问题中的适用性和合理性。结果表明，该方法可为小型卫星部件布局设计提供有效的解决方案，同时兼顾质量特性和基频特性优化。

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
