The embodiment of the invention provides an overload adjusting device for a microgravity test. The overload adjusting device comprises a cabin falling platform mounting plate; the cold flow spray pipe is located below the cabin falling platform mounting plate, the cold flow spray pipe is provided with a cold flow spray pipe inlet, a secondary flow inlet and a cold flow spray pipe outlet, and the cold flow spray pipe is used for spraying high-pressure gas; the high-pressure gas cylinder group, the primary pressure reducing pipeline and the secondary pressure reducing pipeline are respectively positioned on the cabin falling platform mounting plate, one end of the primary pressure reducing pipeline is connected with the high-pressure gas cylinder group, and the other end of the primary pressure reducing pipeline is connected with an inlet of the cold flow spray pipe; one end of the secondary pressure reduction pipeline is connected with the primary pressure reduction pipeline and used for conducting secondary pressure reduction on the gas, and the other end of the secondary pressure reduction pipeline is connected with the secondary inflow port. Through a secondary cold flow method, the magnitude and direction of thrust are adjustable, and in the microgravity environment test process, the magnitude and direction of microgravity of a microgravity falling cabin are controlled by adjusting the magnitude and direction of the thrust of the cold flow spray pipe, and the controllable microgravity level is achieved.
