Study on Distributed Gear CAD System Based on Component Technology

根据齿轮零件加工的特点,提出了基于分布式组件技术研制齿轮CAD系统的思想,采用"积木式"组合方式构建了齿轮CAD系统的总体集成框架。设计了一种齿轮模数选择的自适应调整加权系数优化算法,论述了DCOM分布式组件设计,以及三维参数化特征建模和数据同步修改等关键技术。通过组合不同功能的组件模块快速定制具体应用设计系统的方法,可使已开发的分布式齿轮CAD系统作为一个标准模块集成到更复杂的设计系统中,充分体现了分布式组件技术的灵活性和开放性特点。

According to the characteristics of gear manufacture, a general architecture of distributed component technologies based gear CAD system is worked out in the mode of assembled method of 'building block'. A selfadapting optimized algorithm is put forward to select the modulus by adjusting the weighting coefficient. Some key techniques are described, which include the design method of distributed component object model (DCOM), the 3D feature modeling, part drawing and the data synchronizing. To assemble different DCOM, a customized product design system can be rapidly implemented. An agility and openning construction method is proved that this system can be fastly integrated into a more complex product design system in the same way.
