Title: Three-dimensional tolerance analysis of engine based on Jacobian-Torsor statistical model
Abstract: The working mechanism of an engine is the target of analysis in order to consider geometric tolerances which cannot be handled by traditional tolerance chains in engine assemblies. The Jacobian-Torsor model is introduced,and variations and constraints of torsors for features and their joints under the restrictions of size and geometric tolerances are built. Based on Monte Carlo simulation,three-dimensional tolerance analysis for working mechanism with a statistical way is achieved. Compared with traditional tolerance analysis methods,the method based on the Jacobian-Torsor statistical model takes more geometric tolerances into consideration and obtains more accurate results. This model can build the relationship between tolerances of parts and engine performance from tolerance chains' perspectives.
