通过对国内外现有拖网绞机的结构、标准和实例剖析 ,提出基于“拓扑模型”抽象的结构方案设计和基于功能推理和形态学矩阵相结合的原理方案设计作为拖网绞机概念设计理论模型 ;依据系统求解平台 ,研究了基于 C/S/S结构体系的拖网绞机分布式知识库处理系统 ,凭借现有的 Internet/In-tranet和 Web技术 ,实现分布于异地的基于拖网绞机知识库的智能概念设计求解。提出的拖网绞机概念设计模型对于规范拖网绞机产品设计、新标准制订以及产品创新提供理论参考 Through the analysis of the structure, standard and example of the existing trawl twisting machine both at home and abroad, this paper proposes a structural scheme design based on “topological model” abstraction and a conceptual scheme design based on functional inference and morphological matrix as the conceptual design theory model Based on the system solving platform, the distributed knowledge base processing system of trawl cutter based on C / S / S structure system is studied. With the existing Internet / In-tranet and Web technology, the knowledge of trawl cutter Library concept of intelligent design solution. The proposed conceptual design model of trawl cutter provides theoretical reference for standard trawler cutter design, new standard formulation and product innovation
