A ground test system for simulating electromagnetic-eddy current racemization of a space target comprises an electromagnetic field generation device, a vacuum container, a rotating mechanism and a space target simulation part. The space target simulation part is arranged in the vacuum container, and the electromagnetic field generation device is arranged on the side edge of the vacuum container; and the rotating mechanism comprises an air injection mechanism, an air impeller and a high-precision air bearing, the space target simulation part is fixedly connected with the high-precision air bearing through a positioning cone at the bottom of the space target simulation part, the air injection mechanism injects air to drive the fan impeller in the center of the bottom of the high-precision air bearing, and then the space target simulation part is driven to rotate to simulate a space target freely rotating in a vacuum environment. The electromagnetic field generating device is made of a high-temperature superconducting material, so that higher controllable field intensity can be realized, and a servo guide rail and a servo turntable can simulate a relative motion state with the target.Controllable large-field-intensity electromagnetic field generation and effective simulation of the long-time free rotation state of the target can be realized, and the system is suitable for electromagnetic-eddy current racemization test verification of the space target.
