<P>PROBLEM TO BE SOLVED: To provide a torque measuring device and a torque measurement method capable of reliably measuring output torque of an object to be measured with high accuracy by quantitatively evaluating disturbance of waveform components of the output torque due to poor connection and surely determining whether or not the poor connection is present. <P>SOLUTION: An inventive torque measuring device 10 comprises: a connection part 11 connected with an output part 2 of an object to be measured 1; a rotation drive part 12 for imparting rotary drive force to the output part 2 while maintaining the state of connection part 11 connected with the output part 2; and a torque waveform measurement part 13 for measuring the output torque waveform of the object to be measured 1. Furthermore, the torque measuring device 10 comprises: a frequency analysis part 14 for performing frequency analysis of the output torque waveform measured by the torque waveform measurement part 13; and a connection quality determination part 15 for determining whether or not the poor connection is present between the output part 2 and the connection part 11 based on the analysis result of the frequency analysis part 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
