摘要
本文以风机设计中叶轮轮盖和进风口为研究对象,分别用几何展开法和古鲁金定理对回转体侧面积进行计算比较,得出了应用古鲁金定理可以准确、快速地求解回转体侧面积。
In this paper,set impeller cover and air inlet as the research object in fans design,geometric expansion method and P.Guldin theorem are respectively used to calculate and compare the side areas of rotary components.The conclusin is obtained that the application of P.Guldin theorem application of can accurately and rapidly solve the calculation problem of the side area of rotary components.
