To provide a diagnosis support device capable of easily estimating the cause of vibration of a device by using a qualitative state representation.SOLUTION: The diagnosis support device 1 executes: a first process of calculating a frequency spectrum from vibration waveform obtained by a vibration sensor 101 attached to a device 100 and extracting a combination of a peak frequency and a peak amplitude in the frequency spectrum; a second process of creating a keyword consisting of a combination of a component name for the peak frequency and a state representation for the peak amplitude from the combination of the peak frequency and the peak amplitude; and a third process of extracting event data including words synonymous with the keyword and displaying them on a display 4.SELECTED DRAWING: Figure 1 【課題】定性的な状態表現を利用して機器の振動の原因を容易に推定することができる診断支援装置を提供する。【解決手段】診断支援装置１は、機器１００に取り付けられた振動センサ１０１で得られた振動波形から周波数スペクトルを演算し、周波数スペクトルにおけるピーク周波数とピーク振幅との組み合わせを抽出する第１の処理と、ピーク周波数とピーク振幅との組み合わせから、ピーク周波数の成分名称とピーク振幅の状態の表現との組み合わせからなるキーワードを作成する第２の処理と、キーワードと同義の言葉を含む事象データを抽出して表示器４に表示させる第３の処理を実行する。【選択図】図１
