摘要: :论文是以功率超声珩磨装置的参数化建模为例,在一般零件参数化设计的
基础上,提出了一种基于草图装配和草图约束的参数化设计方法。此方法是利用UG 建模里
的草图功能,在对零件模型进行几何约束和尺寸约束的基础上,用函数表达式建立多个零部
件的变量尺寸与装配草图的关系,通过对装配草图里设计变量尺寸的管理,实现整个装置零
部件之间的联动。

Abstract: This paper puts forward a parametric design method based on sketch assembly and
sketch constraint by taking the parametric modeling of power ultrasonic honing device as an
instance. This method uses the sketch function of UG modeling to conduct geometric constraint
and size constraint on parts’ models so as to , establish the relations between the variable sizes of
multiple parts and assembly sketches in function expressions. It can realize the linkage between
assembly parts by managing the variable sizes in the assembly sketches.
