摘要

A new structure of magnet - electric induction torsional vibration measurement device is designed,which can directly convert the instantaneous torsional vibration of gear transmission system into the corresponding electrical signal. The mechanical structure and operation principle of this device is introduced,and the output characteristic is induced. The instantaneous torsional vibration of gear transmission system under no load、rated load and variable voltage speed control is measured directly by this device,and the operation principle of this device is verified through the experiments. The measurement results are analyzed by spectrum,the results show that the amplitude of main components of instantaneous torsional vibration is decreasing with the decreasing of power voltage.%设计了一种新结构磁电感应式扭振测量装置，可以直接将被测齿轮传动系统的瞬时扭振转化成相应的电信号输出。详细介绍了测量装置的机械结构和测量原理，并推导了其输出特性。对实际的齿轮传动系统在空载、额定载荷以及调压调速多种工况下的瞬时扭振进行了直接测量实验，验证了测量装置工作原理的正确性。对瞬时扭振测量结果进行了频谱特征分析，结果表明在动力源调压调速工况下，瞬时扭振主要分量的幅值随着电压的减小而减小。
