A detachable multi-order resonance track roadbed dynamic vibration absorption assembly. A cover plate assembly (1) comprises two or more multi-order resonance units (2). Each multi-order resonance unit (2) comprises resonance mass bodies (3) and resonance elastic elements (4) having two or more stiffness-to-mass ratios or no less than two modes. The multi-order resonance units (2) are arranged along the track direction in the form of combining two or more multi-order resonance units (2) together. The multi-order resonance units (2) are fixed on a track roadbed board (5) by means of constraint elastic anchors (6). The equivalent stiffness of the constraint elastic anchors (6) is less than the minimum resonant stiffness of the multi-order resonant units (2). Compared with the prior art, the multi-order resonant frequencies comprises multi-order excitation frequencies during train operation and inherent characteristic frequencies of the track structure during train loading, thereby resolving the problems of complex actual multi-band vibration and noise radiation that are difficult to resolve using conventional vibration absorption measures in track vibration absorption and noise reduction, especially the low-frequency vibration of the track roadbed structure caused by a track vibration isolation system.
