| Abstract:Based on finite element method, mechanical property of the frame and the loading arm of press section was analyzed in this paper. The deformation and stress distribution of the frame and loading arm were obtained through the Static analysis, and the static loading stiffness was checked. Through modal analysis, the modal frequency and modal shape of the frame were obtained. The optimum operating speed（880 m/min）of the model fram was found. With the analysis of the modal frequency another speed-increasing space of 600 m/min was presented if the frame could run smoothly over the 1st sub step modal frequency. This research can not only provide a theoretical basis for the design and manufacture of high speed paper machine, but also offer numeric reference for optimizing the operation and speed increasing rebuilding of exist paper machine. |
