NATURAL-OSCILLATION MEASUREMENT DEVICE

摘要

This natural-oscillation measurement device for measuring the natural frequency of a belt (101) is provided with: an acceleration sensor (11) which is attached to a portion of the belt (101), said portion being positioned between neighbouring pulleys (102, 103), and which detects acceleration due to oscillation of the belt (101); and a measurement instrument (13) for measuring the natural frequency of the belt (101) on the basis of the acceleration detected by the acceleration sensor (11).
