High-precision multi-line spectrum vibration absorber

The invention discloses a high-precision multi-line-spectrum vibration absorber which comprises a supporting column and a plurality of vibration absorbing assemblies. Each vibration absorption assembly comprises a corresponding elastic connecting piece and a mass body, and the mass bodies are located at the tail ends of the elastic connecting pieces and connected to the upper portions of the supporting columns through the elastic connecting pieces. The vibration absorption assemblies are independent of one another and are designed for a target line spectrum. Each vibration absorption assembly is of a symmetrical structure so that the gravity center of the vibration absorption assembly can be located in the center of the supporting column. The supporting columns and the vibration absorption assemblies are of an integrated structure. According to the vibration absorber, the vibration absorption effect can be achieved for multiple line spectrums, meanwhile, an integrated structure is adopted, high-precision manu
