Abstract

The invention provides a twelve-degree-of-freedom space simulator butt-joint performance testing device. The device includes a two-dimensional horizontal movement driving unit, an active yawing driving unit, a passive yawning driving unit, an active space simulator body and a passive space simulator body; the active and passive yawing driving units are arranged at the two ends of the two-dimensional horizontal movement driving unit respectively, the active space simulator body is arranged on the active yawing driving unit, and the passive space simulator body is arranged on the passive yawingdriving unit; the active yawing driving unit drives the active space simulator body to simulate an active end of a butt-joint mechanism; the passive yawning driving unit and the passive space simulator body simulate a passive end of the butt-joint mechanism. Movement coupling among the degrees of freedom of the space simulator is small, the implementation of each degree of freedom is sensitive andreliable, the movement range is wide, the movement track is not limited, and by adopting an air flotation technique, the simulation precision is high.

Description

technical field [0001] The invention relates to the field of aerospace ground simulation experiments, in particular to a 12-degree-of-freedom aerospace simulator docking performance test device. Background technique [0002] In order to test the docking performance of the third-phase lunar exploration docking and sample transfer subsystem under normal temperature conditions, it is necessary to provide equipment for ground test research and test verification. The equipment needs to have two aerospace simulators with three translational and three rotational degrees of freedom respectively, and at the same time satisfy the simulation of the physical properties of the motion of the real aircraft. However, there is no high-precision aerospace simulator with six degrees of freedom at present. The existing six-degrees of freedom aerospace simulators often use liquid flotation and flexible cable suspension methods. The liquid flotation method can only be suitable for certain aeros...
