【摘要】:從物理模型、數(shù)學模型和優(yōu)化算法三個方面系統(tǒng)闡述了結構拓撲優(yōu)化的基本原理.通過實例介紹了應用拓撲優(yōu)化技術進行橋梁結構找型的方法,并展示了拓撲優(yōu)化中結構衍化過程及優(yōu)化結果.針對目前結構拓撲優(yōu)化技術運用在橋梁找型中所面臨的困難,探討了未來研究的方向.研究表明,結構拓撲優(yōu)化方法可以在橋梁概念設計階段得出合理而新穎的結構形式,在橋梁找型方面具有良好的應用前景.
[Abstract]:The basic principles of structural topology optimization are systematically expounded from three aspects: physical model, mathematical model and optimization algorithm. This paper introduces the method of bridge structure type finding by using topology optimization technology, and shows the evolution process of structure and the result of optimization in topology optimization. In view of the difficulties faced by the application of structural topology optimization technology in bridge search at present, the future research direction is discussed. The results show that the structural topology optimization method can obtain a reasonable and novel structure form in the conceptual design stage of the bridge, and has a good application prospect in the field of bridge type finding.
