该系统的目的是辅助材料工艺条件的决策，以制造出具有良好冲压成形性的板材。该系统采用有限元分析与离散优化算法相结合的方法实现。在这个系统中，优化算法需要快速搜索到最优条件。因此，新提出了响应面法来提高检索效率。该系统用于寻找适合于板成形条件的退火条件。选择退火温度和时间作为工艺参数。通过冲压件的厚度均匀性来评价成形性。结果表明，该系统能快速搜索到最佳工艺条件.通过实验验证了该系统的有效性。实践表明，该工艺优化设计系统是一个确定材料工艺和板料成形设计的有效工具。
The aim of this optimum process design system is to assist the decision of material process condition for making a sheet metal which has better formability for stamping. This system is realized by combining finite element analysis and discretized optimization algorithms. In this system, optimization algorithm is required to search the optimum condition quickly. Therefore, the response surface method was newly suggested to improve the efficiency of the retrieval. This system is applied to find the annealing conditions suitable for a sheet forming condition. Annealing temperature and time are chosen for the process parameters. Formability is evaluated by thickness uniformity of stamped part. As the result, this system could search optimum condition quickly. The effectiveness of this system was confirmed through experimental verification. It is demonstrated that this optimum process design system is a useful tool for deciding a material process and sheet metal fabrication design.
