Abstract

Geometric parts of mechanical assembly are not manufactured precisely. Two uncertainty measures are especially interested for the defects representation: the distribution of the uncertainties that one piece can be manufactured at dimension X, and the likelihood that the assembly respects the functional constraints. This paper deals with the use of fuzzy logic for the representation of tolerances. This new method is an extension of the worst case and statistical kinematic analysis. It simplifies the equations of maximum likelihood which generally uses complex Gaussian distribution and is an easy understood representation of uncertainties. We treat the case of connecting rod — crank assembly as an example.
