Abstract: This paper studies the outline optimization for the circum-shell of compounding funnel.The internal forces with non-bending, bending moment and friction of the hyperboloidal shell are analysed. A numerical example is presented and the results are in good agreement with those obtained by other methods. The feasibility of the result is indicated.

Key words: hyperboloidal shell, funnel, internal force
