プレス絞り加工のCAEモデル簡略化によるパラメータ設計の効率向上

抄録

CAE has come into wide use as an efficient design tool, and CAE tools incorporating quality engineering have been developed to obtain robust designs. When quality engineering is applied in actual CAE work, however, the necessary calculations take an extraordinary amount of time if ordinary CAE models are used. This problem was attacked in a parameter design study carried out for a deep drawing process by CAE. The study showed that good reproducibility could be obtained by use of the sheet thic㎞ess reduction ratio in the deep drawing process as a characteristic value, which provided a guideline for simplifying the CAE model in the parameter design. As a result, it was possible to show how to make CAE more efficient in a concrete case, the problem that had hampered the use of CAE in parameter design was solved, and a contribution was made to the application of quality engineering to design work.
