摘　　要：本文通过汽锤力载荷的简化计算方法求解汽锤载荷力。应用PIPENET软件对国内某三代核电厂蒸汽发生器到主蒸汽母管之间的蒸汽发生器系统进行建模。利用瞬态计算功能模拟汽锤发生及衰减过程,给出最大汽锤压力、管系中最大汽锤载荷、该载荷发生的时间及管道位置。并与西屋公司的管道应力计算文件进行对比分析,验证了该计算方法。Steam hammer load is solved though the simplified calculation. And a mathematical model of main steam system in a domestic generation three nuclear power plant is established using PIPENET software, and the model established from steam generator outlet to main steam header. Steam hammer occurrence and reduction is simulated through transient calculating function. Parameters are calculated including the maximum steam hammer pressure, maximum steam hammer load, occurrence time and position of maximum steam hammer load. And compared with Westinghouse piping stress calculation report, the calculation method has been verified.
