车用发动机曲轴CAD/CAM系统的研究与开发

Research in and Development of CAD/CAM System of Automobile Engine Crankshaft

介绍了一种基于微机环境的车用发动机曲轴CAD/CAM集成系统的总体方案设计。着重讨论了零件基于特征参数化设计的设计思想、实现策略和关键技术 。

The general plan of Crankshaft CAD/CAM system based on the microcomputer is introduced. The design,application strategy and key technology of the design subsystem based on feature parametrization for Crankshaft are discussed in detail.Based on the method of feature-based solid modelling technique,a kind of graphics modelling method suitable for each form feature and an idea based on the parametric combined graphics elements are presented,which can be of great consultative value to CAD/CAM integration system based on the microcomputer.
