In order to solve the problems of long construction time,large floor area and high cost caused by hydraulic vibration test system,the double-direction hydraulic vibration test system with damping base was proposed and developed.The structure and working principle of the doubledirection hydraulic vibration test system were introduced,and the structure of the core components such as the damping base,the servo actuator device was expounded in detail;according to the technical index requirements and national metrological vibration regulation JJG 638-2015,0.5~200 Hz/4g sine sweep test was carried out for the hydraulic vibration test system.The core performance indexes of the system,such as the distortion of acceleration,the uniformity of acceleration and the lateral vibration ratio of the table,were tested.The test results show that the core performance indexes of the system meet the requirements of JJG 638-2015.
