摘　　要：以核电汽水分离再热器(MSR)U形管束为研究对象,全面分析了管束振动的机理,着重从理论上探讨了MSR管束振动校核方法,形成一套系统的校核体系,并提出了相应的抗振措施,可直接用于指导MSR管束的工程设计。Taking the U-tube bundle of steam-water separation reheater(MSR)of nuclear power heat exchanger as the research object,this paper comprehensively analyzed the vibration mechanism of the tube bundle,emphatically discussed the checking method for the vibration of MSR tube bundle in the perspective of theory,formed a systematic checking system,and put forward the corresponding anti-vibration measures,which can be directly used for guiding the engineering design of the MSR tube bundle.
