Application of FEM in Analysis of Spigot Joint Contact Problems

Summary

The conventional designing process of axial-symmetrical connections does not take into consideration the manufacturing errors of connection elements. Here we take measurements of elements that are parts of pin and spigot joints, showing the incomplete contact of surfaces of interlocking parts. Computational models are used to analyse the cooperation of elements of axial-symmetrical connection. We make use of the engineering system I-DEAS with FEM and contact element modules. The resulting parametric computational models enable us to correct the experimental values and to evaluate the contact stresses more accurately.
