The invention discloses a multi-degree of freedom air floated platform pressure stabilizing device and a pressure stabilizing method, belongs to the field of whole physical simulation and solves the problem of complex control structure, poorer control accuracy and lower pressure stabilizing ability of the existing multi-degree of freedom air floated platform. The multi-degree of freedom air floated platform pressure stabilizing device comprises an air floated shaft. The air floated shaft comprises an air floated bearing outer sleeve and an air floated bearing inner sleeve. The air floated bearing inner sleeve is installed in a hollow air cavity of the air floated bearing outer sleeve, and the air floated bearing inner sleeve performs movements in the vertical direction along the inner side wall of the air floated bearing outer sleeve; the upper end of the air floated bearing inner sleeve is connected onto the air floated platform; nozzles are installed on the inner side wall of the air floated bearing outer sleeve; a pressure sensor used for measuring the pressure in the hollow air cavity is arranged on the inner side wall of the air floated bearing outer sleeve; the nozzles and the pressure sensor are positioned between the lower end of the air floated bearing inner sleeve and the lower end of the air floated bearing outer sleeve. The multi-degree of freedom air floated platform pressure stabilizing device also comprises a cylinder, a first-level pressure reducing valve, a second-level pressure reducing valve, a proportional electromagnetic valve, a third-level pressure reducing valve, a switch and a benchmark air cavity. The multi-degree of freedom air floated platform pressure stabilizing device and the pressure stabilizing method are used for all physical simulation tests.
