中文摘要: 我国航天器发展战略重视原始创新和总体优化,其中多舱段(或多支撑面)航天器舱的设备(简称组件)总体布局优化问题提到日程。它是研究如何将组件集合中组件分配到各单舱段(组件分配)和组件在单舱段布置(组件布置),以及二者集成的总体布局优化问题。难点一是该问题属于系统布局优化,为此从系统建模角度,建立该总体布局优化并行协同进化框架和多层系统模型统领全局。难点二是组件分配与布置二者间存在循环相互依存耦合关系,实质是互为对方泛函问题。组件分配优劣需用总体布局系统评价,为此用粗粒度总体布局优化模型快速给出其评价依据并附总体布局结果,然后用细粒度模型再总体优化,并给出粗、细粒度二者模型协同的协调机制。难点三是要面向应用,为此进一步仿卫星工程师设计模式给出具针对性知识融合方法,基于卫星舱总体布局仿真平台再最后优化。以卫星为例给出设备分配与布置集成总体布局优化理论与方法,为一类航天器舱总体布局优化提供技术支持。

英文摘要: The strategies for developing spacecraft of our country emphasize original innovation and overall optimization. The overall layout optimization of instruments (components) in multi-cabin (or multi-panel) spacecraft has been put on the agenda, which includes how to distribute all components into each cabins (called component distribution), how to palce these components distributed to the same cabin (called component placement), and how to holistically optimize component distribution and component placement. One of the difficulties is that this problem belongs to system optimization, therefore, from the system modeling perspetive, a parallel coevolution framework and multilevel system model need to be built for commanding overall arrangements. The second difficulty lies in the annular interdependent coupling between component distribution and component placement, i.e. one is the functional of another one. The result of component distribution should be evaluated by overall layout system, therefore, a overall layout optimization model based on coarse granularity is adopted to quick provide evaluation criteria alongwith the result of overall layout. Then a fine granularity model is adopted to overall optimize again, and the coordination mechanism should be proveded for coarse granularity model cooperating with fine granularity model. The third difficulty is that the research should be application oriented, therefore, a targeted knowledge fusion method should be provided by imitating design mode of satellite enginner, and the final optimization is performed on the overall layout simulation platform of satellite module. This study yields eventully integrated overall layout optimization theory and methodology for both component distribution and component placement within a satellite module, which attempts to provide technical support for the overall layout optimization for a kind of spacecraft module.
