The invention discloses a device used for testing the static and dynamic performance of a damper. The device comprises a main machine part, a measurement and control part and a hydraulic part, wherein the main machine part is used for executing and achieving the test on the static and dynamic performance of the damper, the measurement and control part is used for controlling the main machine part to test the static and dynamic performance of the damper, and the hydraulic part is used for providing a hydraulic energy source for the main machine part to carry out the test on the static and dynamic performance of the damper. The device can effectively improve natural vibration frequency of a mechanical part, reduce the influence on the test accuracy from the vibration of the testing device, meet the requirement for the high-frequency power test, and achieve high-accuracy test on the static and dynamic performance of the damper under actual environmental conditions.
