| Abstract: | By using finite element analysis software ANSYS,the 3-D model of real structure of waste heat boiler was built when the effect of tubesheet interacted with cylinder and tube was taken into account.Based on the mechanical stress analysis,the deformation of the tubesheet and the stress distribution diagram were obtained.Then,the results were treated with linearization method and assessed with the rules of stress classification specified in JB4732. |
