Genetic Algorithms for TTRS tolerance analysiscally Related Surfaces (TTRS) concept represents and classifies part surfaces and mechanical assemblies. We show results for examples with position and orientation tolerances that suggest that a Genetic Algorithm approach can provide an effective means for tolerance analysis.

3D Tolerances Analysis, from Preliminary Studyan be 3D position tolerances, clearances...), enables us to calculate functional conditions on the assembly..3D tolerance analysis is performed like a unidirectional chain of dimensions, with computed coefficients (sensitivities) that fully take into account the 3D effects. Results are presented as

Statistical Tolerance Analysis Using GapSpacetured dimensions with a joint probability density function, assembly analysis is performed by integrating the density function over a tolerance region or assembly region described in GapSpace. Through an example, this paper addresses how statistical tolerance analysis should mimic the “manufacturing

Simultaneous analysis method for tolerancing flexible mechanismsformations of mechanical parts and joints, and internal forces. It can be used in the aim of testing tolerancing and its technological consequences as life cycles or load levels (maximum static equivalent stress, fatigue stress,...). We have to discretize the assembly in elastic parts and joints (a

Tolerance analysis and synthesis by means of clearance and deviation spaces in many cases. A mechanism is considered as constituted of solid bodies and joints. The set of displacements allowed by a joint is called clearance space. It takes into account the degrees of freedom of the joint but also the clearance between the two bodies linked by this joint. For each functiona
