Design Method of Prefabricated Hole Flange-Forming of Hemispherical Shell Parts

Abstract:

Based on the principle of the length unchanged and the principle of the area unchanged in the deformation zone, a mathematical model of the flange-forming prefabricated hole of hemispherical shell parts is established, for the difficult problem of designing the flange-forming prefabricated hole size for hemispherical shell parts. To solve the mathematical model, a numerical method and a software system for the solution of the mathematical model is established. The feasibility of the mathematical model and solving method is demonstrated by the simulation of the typical flange-forming of Hemispherical Shell Parts.
