The invention provides a method for separating vibration transmission of a first sound channel and a second sound channel of a seawater cooling system, which comprises the following steps: integrating the vibration of the first sound channel and the vibration of the second sound channel, isolating the vibration of the second sound channel, replacing a rigid horse leg with an elastic horse leg at a pipeline horse leg mounting part, and fastening and mounting the elastic horse leg and an elastic suspension rod of a sound bridge device; separating the vibration of the first sound channel from the vibration of the second sound channel; starting normal operation of the system; arranging a vibration acceleration sensor for testing to obtain a first average acceleration level of the vibration of the ship structure; elastically suspending the system pipeline; arranging a vibration acceleration sensor for testing to obtain a second average acceleration level of the vibration of the hull structure. According to the technical scheme, vibration transmission of the first sound channel and the second sound channel of the ship mechanical system can be separated, and support is provided for identification of weak links of a mechanical system vibration control scheme.
