Studies on Optimum Design Theories of a Rotary Shaft and the Expert CAD System (Part II)

The Methods of Pareto Evaluation and Performance Simulation

Abstract

In the previous paper, the approximate design on the edge-curve of a rotary blade and the kinematic relationships between rotary blades and soil surface were discussed in order to decide the basic parameters of geometrical motion of rotary blades for the optimum design.
This report deals with the quantification of the performance conditions which must be satisfied as the knowledge source ([knowledge base]) of the expert CAD system and objective functions of optimum blade arrangements. Furthermore, the methods in order to get the set of Pareto optimum arrangements ([data base]) for the efficient design, and their calculation methods of performance simulation will also be discussed.
