摘要
运用有限元方法对具有大直径接管的冷凝器进行了应力分析 ,得到了接管部位的应力分布 ,并按照分析设计原理进行了强度评定 ,针对原设计中的不足 ,进行了多方案计算 ,为该结构的改进提供了依据。
In this paper a stress analysis for a condenser with large diameter nozzle had been made by finite element method. The pattern of the stress distribution of the nozzle region was obtained from the calculation. According to the analysis design principle the strength of the large diameter nozzle was evaluated. As to the lack of original design, multi-variant calculation had been carried on which gave a basis of improving the structure.
