由于端盖形状特殊,很难用解析理论求解.通过大量有限元分析表明,各种类型的凹型端盖,没有太大差异.为弄清端盖设计中的基本原理,文章从壳体的经典理论出发,进行系统研究,通过推导,得出端盖优化设计的一般原则,以指导设计工作.%The authors have analysed various types of head covers commonly used in cast iron dryers when the " Design standard of cast iron dryers used in paper machinery" was formulated first time. Due to the specialty type of dryer heads, il is diffcult to reach a analytic solution, a lot of calculation demonstrate that there are no obvious differences of various types of dryer heads by using finite element method. Baaed on the theory of shells, through theoretical deduction, the rule of optimal design of dryer head covers is proposed.
