THE STUDY OF THE 1MN LEVER-AMPLIFIED FORCE STANDARD MACHINE WITH TRAVELING WEIGHT AND DOUBLE LEVERS

摘要

The paper described the study of the traveling weight, double levers force standard machine, which the maximum load is 1MN. First, the double levers system keep the main lever balance when the displacement of the traveling weight is zero; second, traveling weight is driven by the coordination of some components: ball screws, beam for loading. Displacement transducer and semi-closed loop control are applied to monitor and control the movement of traveling weight and main lever. The machine can apply load according to the displacement of the traveling weight, which is different from deadweight stack with individual mass disk. The experiment data are analysis, and the machine had the advantages of wide measurement range, higher control precision, higher accuracy and better efficiency.
