Elastoplastic Analysis and Optimization Design for the Tube Channel End of Screw Lock Closure Type Heat Exchanger

Abstract:

With the usage of the FEM software ANSYS, an axisymmetric model for the tube channel end of a screw lock closure type heat exchanger was built. The elastic and elastoplastic stress analyses were carried out. The variations of the stress distribution at the root of threads and the contact pressure on threads engaged surfaces were invesgated. Furthemore, an optimization design based on the elastic model for this type heat exchanger was also conducted in order to obtain reasonable structure dimensions and make full use of materials.
