| A CAD system model on the optimization of machine-tool spindle including mechanics model analysis, optimization method, product data management and drawing creation is proposed. Based on OOP technology, it can create mechanics analysis model, optimization model, layout drawing and print with friendly interface automatically, embodied the thinking of agent design.Chapter 1 is a brief introduction on the optimization technology of machine-tool spindle as well as the application and development trend of CAD tech. Based on the brief analysis of current technology's advantage and deficiency, the topic and framework of this issue is proposed.Chapter 2 investigate the current optimization technology of machine-tool spindle system in detail and evaluated the advantage and deficiency objectively. Used the disassembling toy-bricks mechanics model which is more similar to the factual system and the analysis and optimization algorithm easy to be realized on PC, the program on character analysis and emulation of the multi-bearing meta-section machine-tool spindle is created.In chapter 3 a particular analysis on the application and development trend of CAD technology is made and VB programming is selected as the tool of AutoCAD development based on ActiveX Automation. The design scheme and method is also proposed.Chapter 4 and 5 expatiate the three sub-schemas: mechanics model, optimization analysis, drawing layout and output. Based on the analysis on exact character and dynamic-properties of machine-tool spindle's section model, multi-line method is selected as the optimization scheme and the program was writed. The optimization result and final drawing can be got in hard-copy. In addition the concept of product design model is proposed.Chapter 6 is a conclusion of this issue, put forward the future trend, point out some key problems in development and give some suggestions . |
