Abstract

This article describes a method of constructing a refined finite element model of shaft and sleeve assembly structures having a significant distribution in power engineering. Using the developed three-dimensional finite elements, a contact thermo-elastic problem was solved for this type of joints. The displacement distribution field on the end surfaces of the shaft and sleeve, as well as the temperature distribution field in the joint are obtained.

 

Keywords: three-dimensional finite elements, shaft, sleeve, fields of displacements and temperatures, clearance, stress
