Abstract: In the shape optimization design of scroll profiles,
no-rationality of the single object optimization design model is
analysed. A general function of conjugate curves describing the mode of
scrolls based on Whewell equation is presented on the design of
profiles. Alimed at the no-rationality of the single optimization
design, a multiobjective optimization design model is developed.
Nondominated sorting genetic algorithm, based on a sharing niche
technique, is applied. Finally, an example illustrating the
multiobjective shape optimization procedure of scroll profile is given.
Key words: Scrolls Profile optimization Whewell equation
Nondominated sorting genetic algorithm Pareto optimal sets
