The invention relates to the technical field of ships, and provides a vibration absorption system with variable mass and damping decoupling and a vibration absorption control method. The vibration absorption system comprises a supporting platform, a vibration isolation assembly, a vibration absorption assembly and a control assembly. The vibration isolation assembly comprises a plurality of vibration isolators arranged at intervals. The vibration absorption assembly comprises a vibration absorption water tank, a water storage device and a driving device, the vibration absorption water tank is arranged on the supporting platform, a water storage space is formed in the vibration absorption water tank, the water storage device communicates with the water storage space, and the driving device is arranged on a pipeline where the water storage device communicates with the water storage space. The control assembly comprises a controller, an acceleration sensor and a liquid level sensor, the acceleration sensor is arranged on the supporting platform, the liquid level sensor is arranged in the vibration absorption water tank, and the acceleration sensor, the liquid level sensor and the driving device are all in communication connection with the controller. The vibration absorber overcomes the defects that the mass of an existing vibration absorber cannot be adjusted, energy absorption can only be conducted on vibration under the single working condition and the single frequency, and the vibration reduction requirement under the variable working conditions and within the broadband range cannot be met.
