高压容器3种开孔补强方法比较

Com parison of three opening reinforcem entm ethods for high pressure vessel

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。

Three typical opening reinforcem ent m ethods including PVRC, TYM (test yielding m ethod) and PAM (pressure area m ethod) are described .The characteristics ofthese three m ethods and the differences am ong them are m ainly discussed . By com paring and analyzing on a m odelhigh pressure sphericalhead w ith a nozzle subjected to internalpressure using these three m ethods respectively, w e conclude thatPVRCis suitable forsm allopening, w hile TYM and PAM are m ore reasonable and reliable forlarge opening.
