Abstract
In this study, a two-disc shrink fit assembly was modelled in two dimension using ABAQUS/Standard to determine the interfacial pressures with respect to the interferences. Steel—steel and steel—aluminium material pairs were considered. Inner disc of the assembly was considered as hollow and solid shafts, respectively. The results indicate that the finite-element results were in good agreement with the analytical results. In the hollow shaft assembly, both the hollow shaft and the outer disc had non-uniform stress distribution. In the solid shaft assembly, uniform stress distribution for the solid shaft and non-uniform stress distribution for the outer disc were determined. It was pointed out that same pressure can be obtained by different interference with different material pairs. If the assembly has complex shapes, the finite-element method gives more comprehensive and accurate results than the analytical method.
