摘　　要：针对航空发动机叶片锻造成形工艺过程成形阶段多、工艺信息量大、类型繁多等特点,提出了基于多态模型的叶片锻造工艺信息组织方法。对叶片锻造多状态工艺过程进行定义和划分,详细阐述了状态信息的组织形式及状态模型的XML表达方式。给出了基于多态模型的工艺信息集成应用模式,并开发了叶片锻造工艺信息集成平台,以支持叶片锻造多态模型的应用。通过以成形过程中多个状态为节点的组织方式,实现了叶片锻造工艺信息的分类重组,使工艺信息便于管理并适用于实际工艺过程,从而保证工艺过程中数字量传递的逻辑性、连续性和完整性。According to the characteristics of multi-stage forming, more information, variety types for aeroengine blade during forging process, an organizational method of blade forging process information based on multi-state model was proposed. According to the definition and state division of the blade forging process, the organizational form of status information and XML representation of status model were described in detail. Process information integrated application model based on multi-state model was given and the blade forging process information integrated platform was developed supporting the application of blade forging polymorphic model. Through the organizational form by the status of process as node, the classification and the reorganization for the blade forging process information were realized. This could facilitate process information management and be applicable to actual technical process, which could assure digital value transmission the logicality, continuity and integrity during the technical process
