Abstract

Abstract

A mechanical model for calculating tubesheet deformation was established according to the structure of the heat exchanger. The effective elastic constant of the tubesheet was calculated with reference to code ASME Ⅷ-1, the outer cylinder and the heat exchange tube bundle were respectively equalized to springs and elastic foundations axially deforming due to temperature and pressure loads. An analytical solution of tubesheet deflection was obtained with the Ritz method, and compared with the numerical simulation results of 3 heat exchangers of different scales. The results show that, the analytical solution is in good agreement with the numerical simulation results, which verifies the correctness of the derived analytical solution of tubesheet deformation. The research work has guiding significance for the design of fixed tubesheet heat exchangers.
