基于均力结构60MN叠加式力值传递系统

针对60MN力标准机开展国际力值比对的需求,提出了一种带均力结构的叠加式力值传递系统。采用理论和数值模拟的方法分析了力值传递系统中的侧向力分布及均力结构对侧向力的影响,并通过实验进行了验证。结果表明,均力结构不但能减小传递到每个子传感器上的侧向力,而且能将侧向力较均匀地分配到各子传感器上,减小旋转效应对系统的影响。采用均力结构的力值传递系统能满足国际大力值比对与量值溯源的计量性能要求。

The 60 MN Build-uP Force Delivery System Based on ComPensating Structure

For needs of the force value comparison of 60MN force standard machine,the 60MN build-up system is studied. Through theoretical and numerical simulation, analysis on the lateral force distribution and the effect on the compensating structure to the lateral force is analysed, and the validation through the experiment and the international force value comparison is carried out. The results show that using compensating structure can not only reducing the lateral force which is passed on to each load sensor, but also can evenly distribute the lateral force to each load sensor, thus reducing the rotating effect. Reasonable compensating structure design can make the build-up system to have a stable mechanical properties, meet the requirements of both international great force value comparison and the domestic quantity traceability of measuring performance.
