【Abstract】 As the double-rotor centrifuge works its two rotors (internal and external) are rotating under different speeds.Their unbalancing rotary vectors form a resultant rotary vector that produces a beating vibration.The conventional dynamic balancing methods are not fit for this kind of double-rotor centrifuger.This paper describes the beating phenomena of the WL-200 horizontal-screw type double-rotor centrifuge and proposes a beat-relieving method on the basis of correlation analysis.It also presents on the spot a dynamic balancing process applying the above-’ mentioned method with a FT-lB type Fouriare Analyser developed by our university.更多还原
