Abstract
A method for controlling structure-borne noise based on a combined-type vibration isolation device includes the following steps: S1: determining a combined-type vibration isolation device as required according to parameters of a mechanical device to be isolated, and installing the combined-type vibration isolation device on a horizontal bearing surface; S2: vertically placing the mechanical device to be isolated on the combined-type vibration isolation device; S3: adjusting a mass of an intermediate balance weight block of the combined-type vibration isolation device; and S4: adjusting an inherent frequency of the combined-type vibration isolation device to be lower than a structural vibration sound transmission frequency generated in the operation of the mechanical device to be isolated.
