Abstract: Considering the deformation influence is one of the most important research topics of tolerance analysis. The deformation on parts will appear due to the influence of force, temperature and environment in manufacture, assembly and work. The traditional tolerance analysis model based on rigid body has been unable to consider the effect of deformation on tolerance, so it is necessary to research the methods of the tolerance analysis taking into account the deformation. Combined with the research of on tolerance analysis considered the deformation which the domestic and abroad experts are committed to in last twenty years, the methods and models are summarized. The advances of research are reviewed from the representation of tolerance and deformation, method for deformation calculation, tolerance-deformation coupled analysis, and computer-aided tolerance analysis. Some critical issues deserving further research on tolerance analysis taking into account the deformation are also summarized.

Key words: coupled, elastic deformation, representation, thermomechanics, tolerance analysis
