内燃机曲柄连杆机构参数化特征库研究

On parametric feature lib of internal combustion engine crank gear

通过特征的定义、分类及特征库的建立,解决几何模型无法表达非几何工程信息的缺点,并且为曲柄连杆机构中复杂的各种相似零件模型的计算机辅助生成,和信息的重复使用提供实现基础。参数化使得计算机中各种不同模型间的信息交换得以实现。

The disadvantage that non-geometry engineering information can not be expressed by geometry model is solved by definition, classification of feature and foundation of feature lib. And this is the base to generate various similar complex component of the crank gear and the base to information reapplication. Parametric technology makes information exchange between various models become true.
