Rotor profile generation and optimization of screw machines using NURBS.

Résumé

The geometrical representation option for rotor profiles in screw machines provided by the application of non-uniform rational b-splines (NURBS), permits a display format which is suitable for both the approximation of rotor profiles and as part of an optimisation strategy for screw rotors. A comparison of different forms of representation for the crown section of rotor profiles reveals that high representational accuracy of screw rotor forms can be achieved by the use of NURBS, with relatively low information content. This type of representation can be applied both as an optimisation tool for the three-dimensional portrayal of rotor geometries and in rotor manufacturing procedures.
