摘要
采用有限元分析计算方法对受内压圆形筒体小间距大开孔结构的应力分布进行了系列的分析、研究,探索结构应力随开孔率、孔间距及开孔位置等因素的变化规律,弥补了《水管锅炉受压元件强度计算》标准在该方面的缺陷。
In this paper, a stress distribution analysis is made by means of finite element analysis for cylindrical vessels subject to internal pressure. The varying laws of the stress distribution are found out which is subject to opening ratio, space in between the nozzle and the locality, the laws supply a gap of the criterion Strength Calculation of Pressure Parts for Watertube Boilers.
