The invention relates to a method for evaluating a micro-gravity dual-axis gyrator, the dual-axis gyrator consists of an inner ring and an outer ring, and the method for evaluating the micro-gravity dual-axis gyrator comprises the following steps: 11) carrying out physical modeling for the dual-axis gyrator; 12) establishing three coordinate systems of a base coordinate system, an inner ring coordinate system and an outer ring coordinate system, as shown in Figure 2, wherein the base coordinate system is a fixed coordinate system; 13) utilizing the rotating vector properties of the coordinatesystems for finally deriving an apparent gravity acceleration formula of an object, wherein apparent gravity acceleration is the projection of gravitational acceleration under the inner ring coordinate system, and the value is the vector sum of the acceleration and the gravitational acceleration produced by the rotation of the inner ring and the outer ring, and 14) utilizing the apparent gravity acceleration formula and a
