In this paper, the application of restraining beam as waveguide vibration absorber is discussed through theoretical analysis and engineering application, and its application in vibration reduction is analyzed. The damping effect of constrained damping beam is analyzed from the perspective of energy flow. The results show that the restrained beam has the capability of vibration absorption and energy absorption in a wide band and high efficiency.
