These disclosures provide a weight stability control method for a deadweight force standard machine. For each weight in a sequence until all weights are loaded: weight platform is relatively rapidly moved downwards from an initial position, lifting a first-stage weight by a weight disk, and starting to load the first-stage weight starts; the first-stage weight is displaced relatively slowly when the first-stage weight communicates with a second-stage weight via corresponding lifting components for the first time; after the first-stage weight is completely separated from the second-stage weight, relatively rapidly displacing the weight platform downwards again until a gap between the first-stage weight and the second-stage weight reaches half of a pre-set gap value. The method provides control over the stability of the weights, effectively solving the weight shaking problem and improving testing efficiency.
