[0086] A method for determining the effective mechanical impedance of the raft frame structure of the floating raft vibration isolation device of the present invention, the effective mechanical impedance is determined as follows: first, the equivalent raft frame is a simplified model, and then its resonance frequency is calculated, and the frequency band division range is determined; then, the raft frame is calculated, etc. After the efficiency is measured, the impedance value of the sub-frequency band is calculated according to the engineering formula. Taking a floating raft in the design stage of a scheme as an example, the method of the present invention is applied to describe the calculation process of the effective mechanical impedance in detail.
