Abstract:Dryer cylinder head is the most complex pressure parts of dryer in stress analysis point of view, and is the most common area causing dryer accident. Therefore, the research and development of dryer cylinder head have bean attracted great attention. Based on the integral finite element analysis of dryer, compared stress analysis between the commonly used concave dryer cylinder head and convex dryer cylinder head, and compared the main influence factors of dryer cylinder head, such as pressure, breadth and running speed. it was obtained that convex cylinder head dryer could increase the running speed and increase pressure and breadth, and was suitable for high speed wide paper machine, moreover could reduce costs, increase working efficiency, reduce the weight of dryer. Therefore, convex dryer cylinder head is the development trend of paper machine dryer, it provides certain reference for further optimization design of the structure shape of dryer head. |
