Abstract:With the continuous increasing of paper machine speed, roller dynamic performance is very important and it will limit the increase of paper machine speed. The paper analyzed different working conditions and structure parameters and researched dynamic characteristics of dry felt guide roller by using the finite element software ANSYS workbench. It was emphatically investigated that the impact of the length, diameter, wall thickness and bearing supporting stiffness on the dynamic characteristics of the roller. The analysis results indicated that the roller length had greater influence on its dynamic characteristics, and increasing diameter and wall thickness could improve amplitude, but support rigidity almost had no effect on it. Reducing paper machine width and increasing roller diameter could improve the speed, wall thickness affected most obviously the vibration amplitude of the roller. |
