摘　　要：介绍了基于Pro/ENGINEER的纺机常用件设计系统的总体框架,提出了一种设计知识和数据的表达和管理方法。研究了知识管理子系统的信息模型和树型结构的递归算法。最后给出了运行实例,表明系统实现了设计知识和数据的提取、存储、继承和重用,提高了零件设计速度和设计准确性。The overall frame of designing system for staple parts of textile machinery based on Pro/ENGINEER was introduced, and a kind of expression and management method for designing knowledge and data was put forward. The recursive algorithm for the information model and tree typed structure in the knowledge management subsystem has been studied. An operational living example was finally given out, it indicates that the system has realized the picking up, storage, inheritance and reuse of designing knowledge and data, thus raised the speed and accuracy of parts designed.
