In order to solve the problem that the mechanics state simulation experimental procedure and the in-orbit state of an existing space target are not identical, the invention provides a ground physicalsimulation experimental method for space spinning target capture and racemization and belongs to the field of ground zero-gravity simulation of a space control system and a space target. The method includes the steps that the spinning state of the space target is simulated through a six-freedom-degree simulator, and three-freedom-degree motion and the zero-gravity state of a service aircraft aresimulated through air floatation and air jets; a six-freedom-degree mechanical arm carries a spinning tracking paw device to track and capture the spinning angular speed and the spinning axis of the spinning space target; the angular momentum in the capture process is transmitted to the service aircraft, and reverse air jet racemization is adopted; and the actual procedure of in-orbit capture andracemization is completely and identically simulated.
