结构优化方法及其在航空航天工程设计中的应用

Structural optimization method and its application in aerospace engineering design

在航空航天领域,结构优化方法是十分重要的一环,航空航天的飞行器在天空中受到很多物理因素的限制,需要在飞行器设计过程中力求做到造价更低、质量更小以及抗压能力更强等目标。结构优化概念在1900年左右就已经由英格兰著名物理学家J. C.麦克斯韦进行过初步的探索研究。在那个时代结构优化的概念只能在理论上找到一定的存在意义,然而并不能在成果上得到体现。而到了1940年左右"同步极限"理论在航空航天工程设计中被提出。"同步极限"理论就是让组件的设计能达到最极限,让其在航天过程中实际受到作用力后依然能保证各部位均能为最大值状态。

In the aerospace industry,structural optimization methods are a very important part.Aerospace vehicles are limited by many physical factors in the sky.They need to strive for lower cost,lower quality and more pressure resistance in the aircraft design process.Strong and other goals.The concept of structural optimization was studied by the famous English physicist J.C.Maxwell in1900.In that era,the concept of structural optimization can only find a certain existence in theory,but it cannot be reflected in the results.By the1940s,the"synchronous limit"theory was proposed in aerospace engineering design.The"synchronization limit"theory is to make the design of the component reach the limit,so that it can still ensure the maximum state of each part after it is actually subjected to the force in the aerospace process.
