摘要：隨著測試技術(shù)的不斷數(shù)字化、智能化和計算機(jī)化，振動傳感器成為振動測試中的關(guān)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(biāo)準(zhǔn)裝置,在一定的環(huán)境條件下，對參考頻率和參考加速度下的示值進(jìn)行測量，并對振動傳感器加速度的示值誤差測量結(jié)果的不確定度進(jìn)行分析和評定。
關(guān)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
