Unformatted text preview: ith a known nominal form when it is subjected to independent, finished variations (small or otherwise). NB. This perturbation concept is a generalisation of the "small displacement torsor", which represented a variation of the position of a solid body [Ballot et al., 2001]; here a perturbation is finished or infinitely small and, above all, the object is subjected to deformation. Dependence and Independence of Variations 2. TENSOR MODELLING OF GEOMETRIC OBJECTS 25 In modern technology, all the "finished" variation possibilities of an object must be modelled and not simply the variations considered to be "infinitely small". The connections between the elements of this object, seen as a system, must be essentially maintained, in order to preserve its identity through its transformations. From this point, there will no longer be any difference between the dimensional analysis of the object and the tolerance analysis: the same mathematical and computer tool will...
