Using of actual research results of dynamic force measurement and weighing especially the experimental and numerical analysis of dynamic properties of components could allow deeper understanding, improving and uncertainty analysis. The detailed uncertainty analysis of components and complete system requires combined static and dynamic models of the complex system of the whole torque primary standard unit and also need to integrate unwanted disturbing influences like temperature and humidity. Selecting the appropriate type of model and verifying the numerical models of dynamic properties of the load cell, couplings and levers with experimental data is essentially to proof traceability. The results of small force and torque are very promising but need to be extended in range and speed which is not possible by just scaling up but requires new designs and ideas. Our joint project aims to further develop primary dynamic torque standards in the range of 50 to 100 Nm with frequencies up to 50 Hz that are traceable to static fundamental torque standards and to one demonstrator set-up. Besides the metrological importance this field has a great impact on many industrial applications like automotive, green energy and construction. The aim of the German side proposal is to support the set-up of the new primary dynamic torque standard demonstrator by research on combined static and dynamic models of the complex system that are currently not available but necessary the construction, understanding and improvement of the set-up.

利用动态力测量和称重的实际研究成果，特别是部件动态特性的实验和数值分析，可以更深入地了解、改进和进行不确定度分析。部件和整个系统的详细不确定度分析需要整个扭矩基准单元复杂系统的静态和动态组合模型，还需要考虑温度和湿度等不必要的干扰影响。选择合适的模型类型，并用实验数据验证传感器、联轴器和杠杆的动态特性的数值模型，本质上是为了验证可追溯性。小力和小扭矩的结果是非常有希望的，但需要在范围和速度上进行扩展，这不是仅仅通过扩大规模就能实现的，而是需要新的设计和想法。我们的联合项目旨在进一步开发50到100 Nm范围内的基本动态扭矩标准，频率高达50赫兹，可追溯到静态基本扭矩标准和一个演示装置。除了计量的重要性外，该领域还对汽车、绿色能源和建筑等许多工业应用产生了巨大影响。德方建议的目的是通过研究复杂系统的静态和动态组合模型来支持新的初级动态扭矩标准演示器的建立，这些模型目前尚不具备，但对于建立、理解和改进设置是必要的。
