Abstract
Aiming to address the problem of excessive vibration amplitudes of nuclear power plant tubes,which pose significant risks of failure and leakage,a tube vibration reduction test system was developed using impact excitation.Taking DN50 stainless steel pipe as the research object,an impact excitation method adopting a 200 g stainless steel ball with a drop height of 500 mm is adopted.The influence laws of damping parameters(0,3,5,8)and spring wire diameters(0.6 mm,0.7 mm,0.8 mm)on vibration reduction effect are investigated,the effective vibration reduction range of the device is tested,and the sources of test errors are analyzed simultaneously.The results show that the vibration reduction effect first increases and then decreases with the increase of damping parameters,and is positively correlated with spring wire diameter.The optimal vibration reduction performance is achieved at the damping parameter of 5 and spring wire diameter of 0.8 mm,where the vibration velocity of the measuring point is reduced to 26.8%of the theoretical vibration velocity without vibration reduction.The test result can provide quantitative basis and engineering scheme for vibration control of nuclear power tubes.关键词
