基于实例推理的车身夹具智能化设计
Intelligent Design of Body Fixture Based on Case-Based Reasoning
摘要: 车身焊装夹具设计是车身生产制造过程中十分重要的环节。目前的设计方法效率较低，重复性工作较多，而且无法利用以往的设计经验。针对这些问题，开发出基于实例推理的车身夹具智能辅助设计系统。设计工艺文件导入功能以减少重复性工作，结合CBR理论，构建夹具推理设计模块，重点研究了夹具特征知识的表达与存储、知识库系统的构建与管理和基于实例推理技术的夹具重用与参数化求解，最后对系统进行测试并验证了该系统的有效性。
Abstract:
The design of body welding fixture is a very important link in the process of body manufacturing. The current design method has low efficiency, more repetitive work, and can not make use of pre-vious design experience. Aiming at these problems, an intelligent aided design system of body fix-ture based on CBR is developed. The process file import function is designed to reduce repetitive work. Combined with CBR theory, a fixture reasoning design module is built, focusing on the ex-pression and storage of fixture feature knowledge, the construction and management of knowledge base system, and the fixture reuse and parametric solution based on case-based reasoning tech-nology. Finally, the system is tested and the effectiveness of the system is verified.
