摘要：隨著測試技術的不斷數字化、智能化和計算機化，振動傳感器成為振動測試中的關鍵因素，一般可選擇加速度來測量振動。本文以某一型號的測振儀為被測對象，選用比較法中頻振動標準裝置,在一定的環境條件下，對參考頻率和參考加速度下的示值進行測量，并對振動傳感器加速度的示值誤差測量結果的不確定度進行分析和評定。
關鍵詞：振動傳感器；加速度；示值誤差；測量不確定度

Abstract: Along with test technology development, digitization and intellectualization, vibration sensor becomes the key factor in the vibration test. Acceleration test often is used in vibration test. Taking middle-range frequency standard equipment for comparison as example, this article discussed measurement of acceleration and evaluation of measurement uncertainty in the test.
Key words: Vibration sensor；Acceleration；Indication error；Uncertainty of measurement
