大力值宽频带负阶跃力的产生机理及实现方法的研究

\ \ Research on Mechanism and Realization of Large value and Wide frequency range Negative step force

对力传感器承受负阶跃力的机理进行了细致的分析，指出实现大力值宽频带负阶跃力的特殊性，最后创造性地提出了两种实现大力值宽频带负阶跃力的方法，研究结果对建立我国大力值宽频带动态力值计量基准具有重要的意义。

In this paper, the mechanism is studied exhaustively that force transducers bear the negative step force. Then the particularity of realizing large value and wide frequency range negative step force is pointed out. Finally, two kinds of methods that realize large value and wide frequency range negative step force are given out. The results have great significances in building the dynamic force metrological datum in our country.
