The invention provides a design method of a vibration test device for a counter-force connecting rod type actuator. The vibration test device comprises a support assembly (2), a tailstock assembly (3) and a transition plate (4). The support assembly (2) and the tailstock assembly (3) are fixed on the transition plate (4); the method comprises the following steps: S1, determining the height of a connecting port of the tailstock assembly (3) and a tail pull rod lug ring of the counter-force rod actuator (1); s2, the size of a piston rod lug ring lug fork (204) is determined, the size of a support assembly (2) is determined, and the height of the circle center of a stepped through hole is determined; and S3, generating a vibration test device according to the sizes and heights designed in S1 and S2, and carrying out a vibration test. The designed vibration test device is easy to install and operate, a relatively accurate vibration test result is obtained, a high-severity vibration test item is passed, and the vi
