“…In this way, the geometrical restrictions are derived in three parts using a polyhedron: the purely geometrical restrictions imposed by the physical limits of the contact, or the specification of a surface in a zone; the restrictions coming from the load boundary conditions; and the mobilities of the contact. The Skin Model Shapes presented in this work were generated using the tool explained in (Restrepo Garcia et al, 2022), and it has more information about the generation process of the SMS. The algorithms created used in this model will be incorporated in the same platform and they will allow the contact simulation and stability analysis of a system.…”

The variation management and product quality processes are important tasks to guarantee the assemblability of the systems, the scrap reduction and to avoid delays on production and launching. The compound of activities in Geometric Dimensioning and Tolerancing (GD&T) are necessary, especially in the early design stages, to take into account variations of different nature and from different sources. In this paper, an approach for considering the loading conditions in a polyhedral-based approach in tolerancing design is presented. The load boundary conditions are represented as additional displacement restrictions in the deviation space. The restrictions imposed by the physical limits of a system, the ones coming from the loading conditions and the degrees of freedom (DoF) can be all described and represented with a single polyhedron operand. The approach is illustrated using a simplified 2-D model for both ideal and non-ideal geometry. A 3-D model describing an unilateral contact is presented as a case study using Skin Model Shapes. By taking into account geometrical form defects, external loads, and the kinematics of the system, its sensitivity to variations can be reduced even from early design stages.
