In order to solve a problem that the existing mechanical state simulation of a space target cannot realize tasks of effective spin counteraction of the target and multiple repeated trapping of the target, the invention provides a ground physical simulation experiment system for space spinning target trapping and spin counteraction and belongs to the field of ground zero-gravity simulations of space operation systems and space targets. According to the ground physical simulation experiment system for space spinning target trapping and spin counteraction, the space target spinning state is simulated by using a six-degree-of-freedom simulator; the six-degree-of-freedom motion and zero-gravity state of a service aircraft are simulated by using air flotation and air injection; a six-degree-of-freedom mechanical arm carries a spinning tracking claw device to track and trap the spin angle velocity and spin axis of the spinning space target; angular momentum in the trapping process is transmitted to the service aircraft; and reverse air jet is adopted to perform spin counteraction. The structure of the ground physical simulation experiment system for space spinning target trapping and spincounteraction has the advantages that effective spin counteraction can be realized, trapping and spin counteraction can be integrated and the target can be repeatedly trapped for multiple times.
