摘要
研究机械装配中的对称群方法.定义了装配物体特征的对称群.运用对称群知识进行空间推理,产生了关于物体之间的可能关联位置集合的群论结构,得到两个物体能否装配的必要条件,并举例说明其应用.
The symmetry group approach in mechanical assembling is studied. Symmetry group as a feature for bodies in assembling is defined. Making use of the concept of symmetry group, spatial reasoning is implemented and the construction in group theory for sets of possible relative locations among bodies can be developed. The necessary conditions whether two bodies can be assembled are then obtained. An example is given to illustrate the application of the approach.
