摘　　要：基于对虚拟装配环境中装配零件的几何约束关系分析,分别对几何约束的判别、几何约束的确认和装配运动的定位导航进行了深入研究,通过共线约束和共面约束的产生,对装配零件的运动方向和运动空间进行约束,实现了产品虚拟装配过程中的快速精确定位,减轻了操作者虚拟装配操作的难度。Based on the analysis of geometric constraints in virtual assembly environment, and the indepth study of the differentiating and recognition of geometric constraints recognition, and the positioning and navigation of assembly campaign, through the occurrence of collinear restraint and coplanar restraint, to achieve the movement direction and movement of space limitations, the virtual assembly process was achieved in the fast and accurate positioning, thereby the difficulty of virtual assembly operations was reduced.

关 键 词：精确定位 共线约束 共面约束 定位导航
