Research on the 3-Dimensional Grab Design System Based on Case-Based Reasoning

摘要

With the increasing intense competition of mechanical manufacturing market, companies must shorten products design cycles, improve products' quality, and reduce the costs of products. This paper takes into account the characteristics of grab product design and put forward the method the integrate three-dimensional design and case-based reasoning technology for the grab design, and propose the procedure of grab bucket design based on case-based reasoning and apply the method to grab bucket design field, . In the paper, the 3-D grab case library and explore intelligent reasoning module are established. And case-modified technology through Solid Works and its secondary development are achieved. At last, a set of three-dimensional grab design system is developed, which can realize grab virtual assembly, kinematics analysis, interference check, finite element analysis and creating engineering drawings so that it makes the applications of intelligence design possibility.
