摘要：

The description methods of various tolerance zones and kinematic links based on SDT are discussed. The surfacemodels are applied to describe an assembly, and SDT is used to express the relative position between any two surfaces of anassembly; According to the effect of each functional element on the whole functional requirements of products, the 3 -1; dimension-chain is created, and 3-D dimensional and geometrical tolerance analysis for assembly is realized. The engineering example involving 3-D tolerance analysis is given to test the proposed method.
