PARAMETRIC DESIGN OF SINGLE-LAYER ELLIPSOID SHELL

According to the characteristics of the ellipsoid shell sides,using the parametric language of the finite element software ANSYS,developed two types of single-layer ellipsoid shell,and achieved in a given geometric parameters: the longitudinal span S1,the transverse span S2,rise F,ring to the symmetrical area number Kn,radial nodes laps Nx,can determine the shape of single-layer ellipsoid shell. Designing examples show that the parametric design is simple,efficient,practical,and laid a good foundation of ellipsoidal shells designing and analysis of different types by using ANSYS software.
