产品模型中的三维参数化处理技术研究

提出了基于特征构形的三维参数化处理思想.将特征参数化过程和特征造型过程融合在一起,参数化可以分解为单个特征的参数化和特征之间的约束参数化,特征之间的约束基本上是特征横截面生成平面之间的约束,特征横截面在特征横截面生成平面中的位置确定特征局部坐标系到全局坐标系的坐标变换矩阵.用户作了某些修改后,遍历特征构形历史,将相关特征作相应修改,就可得到修改后的模型.

In Product Model Three Dimensional Parametrization Processing Engineering Research

This article proposed three-dimensional parametefization processing thought based on characteristic configuration. The characteristic parametrization and modelling process combine in together, the parametrization may decompose into between the single and restraint parametrization, the restraint basically is between the characteristic lateral section production plane restraint, the characteristic lateral section in the characteristic lateral section production plane position characteristic partial coordinate system to the overall situation coordinate system coordinate transformation matrix. After the user has made certain revisions, the traversal characteristic configuration history will be connected the characteristic to make the corresponding revision and obtain the revised model.
