Ground physics simulation test system for capturing and derotation of space spin targets

Abstract

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.

technical field [0001] The invention relates to a test system for capturing and derotating a space spin target in a ground gravity environment, and belongs to the field of space control systems and ground zero gravity simulation of space targets. Background technique [0002] The year-by-year increase of space failure satellites and debris has greatly occupied precious orbital space, and some of them have relatively high-speed spin properties and large angular momentum, which have brought major hidden dangers to the safety of normal orbiting aircraft. Therefore, the demand for on-orbit capture of space targets is extremely urgent, but the on-orbit capture of space non-cooperative spinning targets has not been successfully implemented so far. very necessary. To carry out physical simulation experiments on the ground, it is necessary to overcome the influence of inaccurate dynamic characteristics caused by factors such as gravity, and simulate the real kinematic state in the ...
