内齿轮泵实体CAD的集成方法

为弥补现行内齿轮泵CAD运用上的缺陷，基于UG三维开发平台，建立了一个能自行修改参数的通用优化设计模型，并给出离散型、整数型设计变量处理上的技巧；依据该模型的优化结果，驱动该泵实体模型的建立或实时更新过程是全参数化和自动化的；最后实例验证了方法、技巧的正确性和通用性。

Method Research on Solid CAD Applied in Internal Engagement Involutes Gear Pump

Based on expiating the applied limitation of current CAD on internal engagement involute gear pump, its universal optimal model allowed for user freewill modification under UG software was firstly constituted, and a particular opinion of processing discrete or integral design parameters has been raised~ secondly the optimal basic structure parameters of this universal optimal model was formed~its solid model and followed relative analyses, emulation, drawing operations were successively created, the process was all-automatic and all-parametric. Finally the correctness and applicability of the methods and opinions have been proved to be valid by the actual examples.
