326 3 次元 CAD を用いた形状最適化システム

元データ 2003-08-05

概要

A system for optimizing the shape of various products by using 3D-CAD has been developed. This shape-optimization system consists of 3D-CAD, a pre- and a post-processor, an analysis solver, an optimization engine, and an automatic geometry-changing tool. The system has three key features : the iterated optimization process is carried out automatically; it can obtain 3D-CAD data as geometry data after optimization; and the parametric function of 3D-CAD is used to change the geometry of a CAD design. As an example application, the system was used to optimize the shape of a pump impeller, and it was found that it saves time and can cut the impeller mass by about 14%.
