高壓容器3種開孔補強方法比較原作者：楊文玲 王俊寶 閆文軍出處：【關鍵詞】高壓容器,開孔補強,應力集中系數,比較【論文摘要】論述了3種典型的開孔補強方法，即PVRC法、實驗屈服法和壓力面積法的特點和不同。對一高壓模型容器球形封頭上受內壓的接管，分別采用這3種方法進行補強,通過比較和分析可知，PVRC法適用于小開孔，而實驗屈服法和壓力面積法對于大開孔則更合理和安全。--------------------------------------------------------------------------------Comparison of three opening reinforcement methods for high pressure vesselYANG Wen-ling1, WANG Jun-bao2, YAN Wen-jun2（1.Tianjin Uni versity,Tianjin 300072,China; 2.Hebei University of Technology,Tianjin 300130, China）Abstract:Three typical opening reinforcement methods inc luding PVRC, TYM(test yielding method) and PAM(pressure area method) are describ ed .The characteristics of these three methods and the differences among them are mainly discussed . By comparing and analyzing on a model high pre ssure spherical head with a nozzle subjected to internal pressure using these three methods respectively, we conclude that PVRC is suitable for small op ening,while TYM and PAM are more reasonable and reliable for large opening.Key words：high pressure vessel; opening reinforcement; str ess concentration coefficient; comparison 符號說明 g...
