Assembly Variation Analysis of Flexible Parts 2001-01-3114
Build variation is an important aspect of vehicle assembly. However traditional variation analysis assumes parts are rigid, leading to overestimation of variations. A finite element analysis procedure to estimate the build variation due to variations of shape, size and mechanical properties of flexible parts is presented. In addition to the part deformation, assembly force and stress can also be calculated by this method. This procedure is illustrated with an example problem.
