From the conclusion , we can know the results can give a same judgment of ship structure safety , adding end shear force can little increase the stress and multi linear adding may make the result worse
这些结论基本概括为：按照各船级社的方法计算，对船体结构的安全性进行评估可以得到相同的判断；对模型局部仍需要进行详细的局部计算；施加端面剪力会略增大计算应力结果； dnv 、 lr多次计算进行叠加。
The break was assumed to be a single tube double - ended and three - tube double - ended shear break . the diameter of the break orifice is 0 . 876mm and 1 . 518mm respectively . the characteristic responses of main thermal - hydraulic parameters , such as primary pressure , secondary pressure , break flow rate , pressurizer level , secondary side level of steam generator and so on , were presented in this thesis
试验再现了核电厂蒸汽发生器单根传热管双端断裂事故和三根传热管双端断裂事故发生后的热工水力现象，给出了事故过程中一次系统压力、二次系统压力、破口流量、蒸汽发生器二次侧水位、稳压器水位、元件表面温度等主要参数的瞬态响应。
