1. A weight stability control method for a deadweight force standard machine comprising a plurality of weight stages connected sequentially from top to bottom and stacked on a weight platform, a first-stage weight of the plurality of weight stages connected to a weight disk via one or more lifting components that are installed in between every two adjacent weight stages of the plurality of weight stages, wherein the weight stability control method comprises the following steps:
S1, performing a no-load stroke in which a weight which is moving is not in contact with a weight which is static, the weight platform rapidly moves downwards from an initial position, the weight disk lifts the first-stage weight, and the first-stage weight starts to be loaded;
S2, performing a loaded stroke in which the weight which is moving is in contact with the weight which is static, and when the first-stage weight interacts with the weight disk via the corresponding lifting components for the first time, the weight platform starts to be relatively slowly displaced downwards;
S3, after the first-stage weight is completely separated from the weight disk, relatively rapidly displacing the weight platform downwards again until a gap between the first-stage weight and the weight disk reaches half of a pre-set gap value; and
S4, repeating steps S1-S3 in the loading process of the first-stage weight for a second-stage weight all through to an nth-stage weight in sequence until all the one or more weights are loaded.
