摘要
模具型腔体设计是涡轮叶片精铸模设计的前提,它直接影响精铸模的设计效率,是一项典型的强经验、弱理论的工作。为叶片递增模型建立特征库、事例库,将专家经验知识化、规则实例化,实现基于事例推理与基于特征推理技术相结合进行叶片模型转换,同时考虑收缩放型,生成型腔体模型,使得模具型腔体设计更加合理,从而提高精铸模的经济性和时效性。
The precondition designing of investment casting mould to turbine blade is to design cavity model which is a difficult job needing more experience and influence the configuration of its mould and process. Using expert system to translate experience and rules into knowledge and case is a good way to solve this problem. The feature and case database for turbine blade are established. By the thought of case resorting and feature technology, the cavity model of investment casting mould designing is more logical and the time of developing cycle shorted.
