我们描述了多分量力-力矩传感器的动态评估。其中两个传感器，可以测量三个力分量，Fx，Fy和Fz，和三个力矩分量，Mx，My和Mz，开发。一个具有实心圆柱形感测元件，另一个具有中空圆柱形形状。在德国的Physikalisch-Technische Bundesanstalt（PTB），使用力矩校准机对其进行静态校准。利用振动台系统和多通道动态分析仪系统对力-力矩传感器的动态特性进行了评价。法向力分量Fz的频率范围非常宽，高达1 kHz，即本研究中的测试频率。然而，横向力分量和力矩分量的频率范围分别被限制在约200 Hz和130 Hz。柱型力-力矩传感器具有高刚度，因此其频率范围比双目型力-力矩传感器的频率范围宽。
We describe the dynamic evaluation of multi-component force–moment transducers. Two of these transducers, which can measure three force components, Fx, Fy and Fz, and three moment components, Mx, My and Mz, were developed. One has a solid cylindrical sensing element and the other has a hollow cylindrical shape. They were calibrated statically with a force–moment calibration machine in the Physikalisch-Technische Bundesanstalt (PTB), Germany. We evaluated the dynamic characteristics of the force–moment transducers by using a shaker system and a multi-channel dynamic analyser system. The frequency range of the normal force component Fz is very wide up to 1 kHz, the test frequency in this study. However, the frequency ranges for the transverse force components and moment components are restricted to about 200 Hz and 130 Hz respectively. The column-type force–moment transducer has a high stiffness and so its frequency range is wider than that of a binocular-type force–moment transducer.
