With the development of reusable launch vehicles, the thermal protection system has been oriented by the idea of incorporate design which involves thermal protection - structure - thrust system. at the same time, the weight proportion of thermal protection system has been reduced, but the working temperature of thermal protection system has been increased
隨著可重復使用航天器的發展，熱防護系統在向著防熱-結構-推進系統一體化設計的方向發展，與此同時，整個防熱系統在總起飛重量中所佔的重量比例也在降低，而使用溫度升高，即要求防熱結構日趨先進。Firstly, there is a full discuss of space aircraft thermal control. the background of the research for this paper is also presented here, in chapter 2, there is a complete discussing of fem realization in numerical heat transfer, including delaunay grids generation and display, two - dimension temperature field function eduction and collectivity compound
首先全面論述了航天器熱控制和熱分析的基本內容，指出本課題產生的工程背景。在第二章中完整地論述了有限元數值計算方法在解決傳熱問題中的實現，包括delaunay網格的生成與顯示，二維溫度場泛函的推導和溫度場的總體合成等。In the design optimization of space equipment satellite systems, there are lots of discrete and integer design variables, the design space is nonconvex and even disjointed, and has multimodality. unfortunately, current mdo procedures or strategies have difficulty to deal with discrete or integer design variables, they are very sensitive to complex design space, have propensity to converge to local optima near the starting point, and can not handle multiple objectives effectively. to overcome these difficulties, this dissertation adopt the idea of coevolution to systematically develop new multidisciplinary design optimization methods based on decomposition and coordination
論文以航天裝備體系及其它復雜飛行器系統的多學科設計優化（ multidisciplinarydesignoptimization ，簡稱mdo ）為應用背景，針對航天裝備衛星系統設計中存在大量離散和整數設計變量、設計空間非凸和不連通、具有多個局部最優點等特點和現有mdo方法過程難以處理離散和整數變量、對復雜設計空間非常敏感、易於陷入局部最優、不能有效處理多目標等缺陷，採用協同進化的思想，系統地進行基於分解協調的mdo方法研究。
