The invention relates to the technical field of spaceflight ground simulation experiments, in particular to a large-scale spaceflight cabin five-degree-of-freedom simulation device for a docking ground test. Comprising a two-dimensional driving unit, an active attitude setting unit, a braking unit, a planar motion measuring sensor and a yaw unit, the active attitude setting unit, the braking unit, the planar motion measuring sensor and the yaw unit are arranged on the two-dimensional driving unit, a 17T aircraft simulation part is located in the braking unit, and an active docking mechanism and a passive docking mechanism are arranged at the two ends of the 17T aircraft simulation part respectively. The active attitude setting unit and the yaw unit are used for adjusting pitching, rolling and Z-direction attitudes of the 17T aircraft simulation part; the docking ring gravity balancing unit is arranged above the active docking mechanism and is used for balancing the gravity of the active docking mechanism in real time; the braking unit is used for braking the 17T flight simulator, and the planar motion measurement sensor is used for measuring motion parameters. According to the invention, the precision and reliability of docking simulation are improved, and the method can be used for verifying the docking characteristics of the manned lunar exploration docking mechanism.
