Unformatted text preview: nd domain In figure 1, {τ} represents the small displacements torsor of the associated surface from the nominal surface. {C1A} is the small displacement torsor of the A surface of the part 1 from the ideal A surface and {C2A} is the small displacements torsor of A belonging to 2. {C1A2} is the small displacement torsor of A. In tolerance analysis, the knowledge of clearance in joints is useful in order to determine the corresponding deviations. The mechanism is defined as an assembly of parts linked by joints as shown in figure 2. Figure 2 Joint and Frames Elastic Clearance Domain and Use Rate Concept Applications 333 The corresponding domain is the set of values of the coordinates of {C2A}. This domain is defined as a list of inequalities (Half space representation) that gives in the 6D space of components (3 translations and 3 rotations) a list of vertices (V representation). In the following, we only show the V representations of the domains. 2.3. Zone and domain As we shown in the previous section, the domain model is the set of small displac...
