taking nuclear fusion reactor as a research object
one novel design method guided by parametric component design and variational assembly logic relation is presented. The parametric design relates to such components as center conductor post
PF coil
TF coil
divertor cassette
blanket
shielding and vacuum pumping. The solid modeling technology is used for all design objects
which will give the users a 3-D visualization. The design system introduced in the paper shows a new design means for agile design of nuclear fusion reactor and will promote the design to a desper stage.
