Unformatted text preview: rfaces of the two parts linked by a joint. But what is a clearance? We can define it as the set of possible displacements between the two linked parts. Those are limited by contact conditions for UR=0, and we 331 J.K. Davidson (ed.), Models for Computer Aided Tolerancing in Design and Manufacturing, 331 – 340. © 2007 Springer. 332 S. Samper, J.-P. Petit and M. Giordano call it (the set) Rigid Clearance Domain. The displacements are the components of the torsor of small displacements of a frame attached to one surface from the other one. 2.1. Substitution surface The model we use is based on the concept of associated surfaces. This one is attached to the measured surface (skin model) with a specific criterion (mean squares, …). In the following, we assume that all surfaces are associated surfaces. We build a frame on each joint (associated) surface of the system as shown in figure 1. Thus, a joint will have two frames, one for each part attached to the joint. Figure 1 Associated Surfaces 2.2. Clearance Torsor a...
