摘　　要：采用保角映射的方法建立了单层扁挤压筒在均匀内压力作用下应力求解的数学模型,并推导出其的解析解,并由算例证实了计算结果和数值解之间的一致性,为寻找扁挤压筒新的设计理论和优化方法奠定一定的基础。A mathematic model for eveluation of single-layer flat container stress under uniform internal pressure is established. The conformal mapping method is employed and an analytical formula is obtained. Good agreement with numerical solution is achieved in an example provided, validating the present solution. The present work is useful for developing new design theory and optimization method for flat containers.
