The invention discloses a method for calibrating central gravitational forces of a spacecraft ground microgravity experiment. The method comprises the steps of calculating the running situation of a spacecraft under different central gravitational force indexes in the ground experiment by utilizing a numerical simulation method; calculating the indexes and determining the upper bound and the lower bound of confidence coefficient by utilizing an observation system; calculating the real movement of space, calculating the confidence coefficient of an experiment result obtained by the numerical simulation method by combining the ground experiment result; comparing the confidence coefficient with the required confidence coefficient in the experiment, determining that a central gravitational force simulator can meet the experiment requirement if the confidence coefficient meets the experiment confidence coefficient index, ending the calculation, submitting a feasible experiment scheme and recording the technical indexes of the central gravitational force simulator; otherwise, restarting the experiment by using a higher-precision central gravitational force simulator. According to the method disclosed by the invention, an analysis means is selected based on experiment equipment for probability calculation and analysis, and thus the selection problem of the central gravitational force simulator for the spacecraft ground experiment can be solved.
