摘　　要：根据有关理论在某圆筒平盖封头压力管受内压作用时 ,对其两大组件 (平盖封头和内压圆筒 )中的应力分布进行了理论计算 ,也对整个结构 (包括焊接区 )进行了不同载荷下应力分布的数值计算。分析了各组件和焊接区的应力分布、可能的失效区域以及失效载荷。The stresses in the cylinder and end plate of a pressure-vessel have been calculated according to the plate theory. Some numerical analysis of stresses under different loads on the pressure-vessel were produced .The stress distributions and failure of the vessel were discussed as well .Meanwhile an approximate failure lond was issued.
