Description
technical field [0001] The invention belongs to the technical field of fretting damage detection, and in particular relates to a fretting damage test device for a heat transfer tube and a support plate with plum blossom holes and an implementation method thereof. Background technique [0002] In the first and second circuits of nuclear power, due to the existence of high-temperature and high-pressure water environment and the structural installation characteristics of components, component failures caused by fretting damage often occur in nuclear power devices, especially the heat transfer tubes and three-leaf blades in steam generators. The fretting impact and wear of plum blossom hole support plates and anti-vibration strips are the most serious. In severe cases, fretting damage of steam generator heat transfer tubes will lead to failure or even rupture of heat transfer tubes, affecting the operation safety of nuclear power plants. [0003] At present, a lot of research ha...
