(V07BT08A036)NEW CURVE OPTIMIZATION METHOD AND ITS APPLICATION TO SHAPE DESIGN FOR DIE CASTING USING A CFD SIMULATION

摘要

We propose a nonparametric curve optimization method based on a genetic algorithm. With conventional curve optimization methods, since the shape of a curve is defined by a finite number of design variables of real numbers and also has only finite flexibility, such methods may not provide the proper optimum curves. In contrast, the method we propose directly treats curves as solutions in the form of functions, without design variables, and can effectively optimize the curves by numerically synthesizing several functions. We demonstrate the effectiveness of the curve optimization method by applying it to an optimum design problem for die casting using a computational fluid dynamics (CFD) simulation.
