本研究项目旨在开发一个基于案例推理技术的专用夹具自动化设计的基本框架。将探索参数化设计和变分设计技术的结合，以实现自动生成夹具结构几何所需的功能。几何约束分析将用于夹具设计生成，它将包括在考虑拓扑和尺寸约束。夹具设计完成后，将对夹具性能进行评估，以确保夹具设计的质量。研究任务包括：(1)夹具设计需求表示；(2)夹具结构分析与建模；(3)夹具设计案例描述与相似性识别；(4)夹具设计案例自动检索与修改；(5)夹具设计验证，包括几何约束与可及性验证、夹具精度与稳定性验证、夹具刚度验证和无干涉验证。该项目对于实现专用夹具设计的自动化以及夹具设计与CAD/CAM的集成具有重要意义。它可以显著缩短生产交货期，提高对产品变化的快速反应能力。

9734908 Rong This research project is aimed to develop a fundamental framework for automating dedicated fixture design based on the case-based reasoning technique. A combination of parametric design and variation design techniques will be explored, in order to achieve the functions required in the automated generation of fixture structure geometry. Geometric constraint analysis will be used for fixture design generation, and it will include both topological and dimensional constraints in the consideration. Once the fixture is designed, fixturing performance will be evaluated to ensure the quality of fixture designs. The research tasks include: (1) fixture design requirement representation, (2) fixture structure analysis and modeling, (3) fixture design case description and similarity identification, (4) automated fixture design case retrieval and modification, and (5) fixture design verifications, including geometric constraint and accessibility, fixturing accuracy and stability, fixturing stiffness, and interference-free verifications. The project is important to automating dedicated fixture designs and to the integration of fixture design with CAD/CAM. It may lead to a significant reduction of manufacturing lead time and an enhancement of rapid responding capability to product changes.
