Research on the Method for 3D Tolerance Analysis Considering Tolerance Principle
摘要
Abstract
A method of considering tolerance principle for three dimensional tolerance analysis was put for -ward.Based on small displacement torsor(SDT)theory and modal interval arithmetic,the tolerance models of size tolerance and geometrical tolerance of the feature of size apply independent principle, envelope require-ment,maximum material requirement,least material requirement or reciprocity requirement,were established respectively.By using the space vector to represent 3D dimension chain, a mathematical model was built to calculate the closed loop tolerance based on space vector loop stack principle.The application of the proposed method was illustrated through presenting an example,the tolerance analysis steps were given,and the availa-bility of the proposed method was proved successfully.关键词
