WEIGHT STABILITY CONTROL METHOD FOR DEADWEIGHT FORCE STANDARD MACHINE

WIPO Patent Application WO/2022/188738

A1

The present invention provides a weight stability control method for a deadweight force standard machine, which method comprises the steps: S1, rapidly moving a weight platform downwards from an initial position, lifting a first-stage weight by a weight disk, and starting to load the first-stage weight starts; S2, starting to slowly displace the first-stage weight when the first-stage weight communicates with a second-stage weight via corresponding lifting components for the first time; S3, after the first-stage weight is completely separated from the second-stage weight, 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; and S4, repeating steps S1-S3 in the loading process of the first-stage weight for the second-stage weight to the nth-stage weight in sequence until all the weights are loaded. The present invention can achieve control over the stability of the weights, effectively solve the weight shaking problem and improve the testing efficiency.
