| Abstract: | The deformation law of the expanding joint of the tube and tube sheets was studied by dividing the complex expanding joint procedure into several deformation super positions ,and an engineering graphic estimation was proposed for the residual contact pressure of the hydraulic expanding joint tubes of heat exchangers with more evident physical meaning and convenient application. The method was not only suitable for ideal elastic plastic materials,but suitable for the normal materials with hardness trend. |
