本文根据热弹性接触理论,用有限元混合法对双层套箍式加氢反应器壳体的热应力进行了初步分析,得到了反应器内筒体、外筒体、球形封头和法兰的应力分布以及内外筒体之间的接触应力分布曲线。提出了内外筒体配合的较合理的过盈量。
In this paper, based on the theory of thermoelastic contact, the thermal stress of the bimodal ferrule hydrogenation reactor shell was preliminarily analyzed by the finite element method. The inner and outer cylinder, spherical head and flange Of the stress distribution and contact stress distribution curve between the inner and outer cylinder. Proposed internal and external cylinder with the more reasonable interference.
