Representation for Characteristic Curves of Hull form Using Immune Genetic Algorithm based on NURBS with Path Curve Parameterization Method

摘要

This study focuses on the characteristic curves representation for thehull form based on NURBS. With view to the problems in the existingNURBS method, the path curve parameterization method is proposedso that the flow field information can be introduced into the designedcurve. The appropriate optimization model is constructed. And theimmune genetic algorithm is used and the necessary improvement ismade in order to reduce the control points. A series of typicalcharacteristic curves of the full-scale hull form representation instancesusing this method indicate that it is feasible and can satisfy therequirements of the engineering design.
