100 N·m NEGATIVE STEP DYNAMIC TORQUE STANDARD MACHINE

Li To, Shang Weilu, Cheng Yongpei, Yan Kangping, Liu Zhong
  • Abstract:
    100 N·m negative step dynamic torque standard machine is used to calibrate the dynamic characteristics of torque transducer. Through measurement of negative step excitation time τ,it can get the inherent frequency ωn. The paper describes the working principle, key technology, test data and the uncertainty analysis of the machine. The specification of machine is as follows: measurement range 100 N·m, τ ≤ 5ms, uncertainty U = 2.64%, k=2.
