Abstract
Provided are a waveform analysis method and a waveform analysis device capable of preventing, in advance, a breakage accident during operation and preventing stoppage due to breakdown of machinery and performing efficient maintenance work by specifying a degraded part from among the parts that constitute the machinery. A waveform analysis deviceis provided with; a signal analysis unitfor performing fast Fourier transform for a signal transmitted from a sensorthat detects a physical phenomenon in the machinery an impulse extraction unitfor extracting an impulse component from spectrum data generated by the signal analysis unit; a display unitfor displaying waveform data including the impulse component extracted by the impulse extraction unit; and a data editing unitfor editing, from data of a waveform including the impulse component displayed by the display unit, waveform data in a range selected via an input unitby a worker, generating a graph displaying a frequency, a time, and the intensity of the impulse component, and displaying the graph on the display unit
