According to the load elastic distortion formula of theory for elasticity shell

making use of small distortion independent action and synthesis theory

built superposition formula of surface distortion produced by radial load and centrifugal load for ESG hollow Be rotor. And built up a long spherical hollow Be rotor with long-polarized and short-equatorial. The long spherical hollow Be rotor designed by radial deformation have a better sphericity in high-speed rotation. Finally

used a sample to show the long spherical hollow rotor's design

processing and survey

which with long-polarized and short-equatorial.
