To provide a vibration analysis device and a vibration analysis system capable of performing vibration analysis while maintaining constant accuracy regardless of the skill level of a user.SOLUTION: A vibration analysis device 1 diagnoses a machine state based on vibrations detected by a measuring device 2. A setting unit 12 sets a target to be diagnosed, a rotational speed, and a determination reference value. A communication unit 13 communicates with the measuring device 2, transmits a trigger for starting vibration measurement to the measuring device 2, and receives vibration waveform data from the measuring device 2. A condition determination unit 16 determines a diagnosis condition from information on the target to be diagnosed. An analysis unit 17 frequency-analyzes data input from the measuring device 2. An abnormality determination unit 11 performs abnormality determination of the target to be diagnosed based on the determination reference value.SELECTED DRAWING: Figure 3 【課題】使用者の熟練度に関わらず一定の精度を保った振動分析が行なえる振動分析装置および振動分析システムを提供する。【解決手段】振動分析装置１は、測定器２によって検出された振動に基づいて機械状態の診断を行なう。設定部１２は、診断対象と回転速度と判定基準値とを設定する。通信部１３は、測定器２と通信を行ない、振動測定開始のトリガを測定器２に送信したり、振動波形のデータを測定器２から受信したりする。条件判定部１６は、診断対象の情報から診断条件を判定する。分析部１７は、測定器２から入力されたデータを周波数分析する。異常判定部１１は、判定基準値に基づいて診断対象の異常判定を行なう。【選択図】図３
