摘要

本文研制了偏心轴扭振定标机。通过扭簧两端的偏心轴产生标准扭振，采用两台伺服电机分别作为驱动电机和加载电机。仿真和试验数据均表明，转速为（0-300）r/min的电机可激发最大10°的扭角幅值。进行了扭振标定的不确定度实验研究，得到扭振幅值的扩展不确定度为1.2% （k = 2）。

Study on the torsional vibration calibration machine with the eccentric shafts

The torsional vibration calibration machine with the eccentric shaft is developed in this paper. The standard torsional vibration can be produced by the eccentric shaft at the two ends of the torsional spring, while two servo motors are employed respectively as the driving motor and the loading motor. Both the simulation and the test data illustrate that up to 10° torsional angle amplitude can be excited by the machine corresponding to (0–300) r/min. The uncertainty experimental study of the torsional vibration calibration is also conducted, and the expanded uncertainty of the torsional vibration amplitude is evaluated as 1.2 % (k = 2).
