高压容器3种开孔补强方法比较原作者：杨文玲 王俊宝 闫文军出处：【关键词】高压容器,开孔补强,应力集中系数,比较【论文摘要】论述了3种典型的开孔补强方法，即PVRC法、实验屈服法和压力面积法的特点和不同。对一高压模型容器球形封头上受内压的接管，分别采用这3种方法进行补强,通过比较和分析可知，PVRC法适用于小开孔，而实验屈服法和压力面积法对于大开孔则更合理和安全。--------------------------------------------------------------------------------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 符号说明　　g
