COMPUTER AIDED DESIGN METHOD FOR CREATING A SURFACE IN A COMPLEX SYSTEM

摘要

This method may be applied by a computer (10) for creating, from a first axisymmetrical surface (30), a second surface (40) belonging to a sub-system of a complex system, this second surface (40) having to observe at least one constraint (24, CM).;This method includes:a step (E20) for modeling the first axisymmetrical surface (30), while observing the constraints (24, CM), with at least one parameter (P), this step including: a sub-step (E23) for discretizing the first axisymmetrical surface (30) in several points, said parameter (P) being a coordinate of one of these points in a reference system associated with at least one portion of this sub-system; anda sub-step (E26) for reconstructing the first axisymmetrical surface (30) from said at least one point and from said at least one constraint (CM);a step (E60′) for modifying said at least one parameter (P) in said reference system for modeling said second surface (40); anda step (E75) for recording said second surface (40) in a memory (17) of said computer (10).
