【摘要】 连杆锤锻模智能CAD系统是基于知识工程技术和最新三维辅助设计软件研制的，它很好地解决了CAD软件和人工智能结合的问题，不仅具有强大的三维造型等功能，而且还能象人类专家一样进行推理、记忆、学习和尝试等思维活动。模具设计极其依赖于设计者的经验知识，同时还需要处理大量复杂的图形和繁琐的数据，因而传统的CAD系统已很难满足实际生产的需要，只有ICAD系统才是企业实现模具设计自动化的最佳方案。因此，连杆锤锻模ICAD系统的研究就有了重要的意义。 本论文从实际设计和生产的角度，对ICAD系统的开发问题做了较深入的探讨与研究，提出了初步的解决方案。在此基础上，根据企业的实际情况及现有技术条件，运用VB6.0、数据库ACCESS97和SolidWorks2001，开发了一符合企业需要的实用化ICAD系统框架，很好地解决了连杆类零件锤锻模设计的问题，并建立了完全开放的设计环境，支持更多同类新产品的设计。 系统的开发严格遵循了软件工程的思想与方法，根据实际需要，将系统在整体上分成七个模块：零件总体信息(部分)输入、冷锻件设计、模锻工步设计、制坯工步设计、模具设计、工艺卡设计和信息库及查询模块，同时还建立了相应的知识库及相应系统。系统在开发过程中及结束后均进行了及时的测试。测试表明，该系统运行平稳可靠，较好地满足了要求，再做进一步开发即能满足企业基本需要。 本论文是对ICAD技术在模具设计中的应用所做的有益探索，对提高企业计算机辅助设计水平，促进企业数字化建设有现实意义，前景乐观。更多还原

【Abstract】 The ICAD system of hammer forging dies for connecting rods has been developed based on KBE and uptodate 3D engineering software. Embodying mighty 3D featuring functions etc, it can do intellillgent work like an expert, including reasoning, learning and so on. So it effectively combines CAD software and artificial intelligent technology. Depending on experience greatly, die design needs to deal with complicated graphics and mass data, the traditional CAD system can not meet the production needs while the ICAD system is the best answer to actuallize die design automation. So it is significative to study the ICAD system of hammer forging dies for connection rods.From practical design and production, the paper has made relatively deep probe and study on ICAD system, and also has put forward primary resolvents. In addition, we have designed and partly implemented a practical system satisfying enterprises’ needs based on actual things and existing technology with VB6, ACCESS97, SolidWorks2001.The design of the system has strictly followed the idea and method of software engineering. In terms of the actual needs, the total system is divided into eight modules: input of parts’ information, cold forging desgin, heat forging design, performing design, die design, processes card design and information base with manangement system. The knowledge base with attched system has been founded as well. Timely testing has been made in the course of design and after the design. The testing indicates that the system runs smoothly and reliable, and meets the demand. It could satisfy the basic demand of enterprises only if further developed.The paper is a beneficial seek in improving the practicality of ICAD application to die design. It has practical worth and a bright future.更多还原
