Abstract
A local stress analysis and assessment for the tube sheet of a heat exchanger with pre-stretching deformation were conducted by using finite element method.The results presents that compared with the heat exchanger without pre-stretching deformation,the local stress in the tube sheet of the heat exchanger with pre-stretching deformation can be reduced sharply.The von Mises stress has a lowest value when the ratio of the pre-stretch deformation to the linear expansion difference of the two materials is about 0.5 ~0.75.The axial stress for the heat exchanger with tubes distributed non-uniformly is larger than that with uniformly distributed tubes.In addition,much attention should be paid to the axial buckling for a shell with a large radius-to-thickness ratio.关键词
