| Abstract: | To study the stress distribution and the safety of a steel dryer in paper making machine, the finite element method was used and the 3D finite element model was built. The stress on the dryer was calculated. The stress distribution contour of the dryer was obtained and the maximum stress was analyzed and evaluated. The results show that the zones with maximum stress occur at the connection area of head with cylinders and inside of boundary stress region of manway opening. |
