厚壁球形封头温差应力分析

Analysis on Thermal Stress of Thick-walled Spherical Head

通过对承受温差载荷的厚壁球形封头进行弹性应力分析,得出了厚壁球形封头温差应力的计算式,并得到了温差应力的分布状况,为高压厚壁球形封头的设计提供了理论基础。

By analyzing the elastic stress existing on thick spherical head beating thermal load, a formula for it and distribution of thermal stress are derived, which provides the thick -walled spherical head with the theoretical basis,
