| Abstract: | Tolerance analysis of parts is an important process in assembly tolerance accumulation analysis. The result of tolerance accumulation analysis is based on the tolerance model of each part. Synthesize method of thermal deformation and geometric tolerance for certain function is studied based on the theory of small displacement torsor （SDT）. A tolerance model is provided for tolerance analysis for tolerance synthesize. |
