Analytical Detection of a Mesh Vertex Being on the Inside of a Round Through-Hole

Abstract

Design is one of the first stages of the PLM process. However, for each newly designed mechanical part, it is essential to test it for durability in different usage conditions (‘stress evaluation’). Before the production of real test samples, it is reasonable to check the model numerically via the 3D Finite Element Simulation method. Even though the simulation produces good results, in certain conditions these can be unreliable. As reported in a previous publication, the reliability of results was checked by the developed AI models. However, it was noticed that due to the modeling specifics the developed models could not distinguish between unreliably evaluated vertices belonging to round through-holes, and reliably evaluated vertices located on inner radiuses. This required development of an algorithm capable to distinguish between these cases. The paper presents the developed analytical algorithm based on geometrical computations and ray tracing. The results are illustrated on components from the automation equipment producer Festo SE & Co KG.
