Automated assessment of the low-rigid composite parts influence on the product assemblability in the GePARD system

Abstract

Abstract Composite components tend to have higher deviations from the nominal dimension in conjunction with metal components. Composites production processes simulation methods have already been developed before long time ago. This article presents the possibility of integrating the technique of non-rigid dimensional chains, taking into account the elastic properties of composite materials to assess the products assemblage with machinery parts from composite materials, on the basis of three-dimensional GePARD system. The fundamental points of the dimensional chain calculating method with non-rigid parts, as well as methods of assessing the stiffness for some types of composite materials, which take into account some peculiarities of its structure, are also examined. The assemblability of an assembly unit is represented by the parameter of the functional assembly requirement depending on the critical accuracy characteristics.
