针对威斯康辛大学AP600 冷凝实验的实验本体进行结构分析,计算其承压能力和密封性能。因通过计算发现实验本体承压性能不足,提出改进实验本体结构的设计方法。通过ANSYS 有限元计算分析了改进后的实验本体的承压性能。结果表明,改进后的实验本体,具有更好的承压能力,可满足更高的实验参数需要。
This paper introduces at first the structure of the pressurized vessel for AP600, which was developed by University of Wisconsin, and the stress and tightness of the pressurized vessel are analyzed. Then an improved structure of the pressurized vessel is developed so that the pressurized vessel can support a higher pressure for the experimental test of steam condensation on the cold surface. The stress of the improved pressurized vessel is analyzed by ANSYS. The calculation result shows that the pressurized vessel can not only support a higher pressure but also meet other thermal measurement requirements of the test.
