本文对一台内直径为１０００ｍｍ、设计压力为３１．４ＭＰａ的带有厚度与筒体不相等半球形封头热套高压容器进行了强度研究，建立了综合考虑半球形封头成形过程中的厚度变化和加强箍与半球形封头贴合质量的有限元应力分析模型，应力计算值和实测值相当吻合，连接接头处没有显著的应力集中现象，加强箍与半球形封头之间圆柱面的贴合质量对容器应力的影响很小，制造时应严格控制锥面的贴合质量。
In this paper, an inner diameter of 1000mm, the design pressure of 31.4MPa with the thickness of the cylinder is not equal to the hemispherical head thermocouple pressure vessel was studied to establish a comprehensive consideration of the thickness of the hemispherical head forming process Change and strengthen the hoop and hemispherical seal quality of the finite element stress analysis model, the calculated stress and the measured value is quite consistent, there is no significant stress concentration joints, strengthen the hoop and hemispherical head between the cylindrical surface The quality of the fitment has little effect on the stress of the container, and the conformability of the conical surface should be strictly controlled during manufacture.
