The invention discloses a cabin structure vibration and air noise forecast verification test device. The device comprises a frame structure, a structure supporting device, structure mounting bases, frequency conversion equipment, vibration reduction elements and a wall sound absorption material. The frame structure is fixed to the ground through the structure mounting bases, and the vibration reduction elements are arranged between the frame structure and the structure mounting bases. A target cabin is reserved in the frame structure. The frequency conversion equipment is fixed in the frame structure through the vibration reduction elements and located outside the target cabin. The structure supporting device is fixed outside the frame structure, and the bottom of the structure supporting device is fixed on the ground. The wall sound absorption material is laid on the inner wall of the frame structure. The accuracy of the vibration noise forecasting method can be verified, and the vibration noise level of the cabin environment can be simulated.
